Until now I used a sharp scalpel to cut the leather when making knife sheaths. The disadvantage is that the thin blade snaps pretty easily, especially when forcing the tip of the scalpel around sharp corners.

I thought about buying a half or quarter moon knife (leather round knife) for my work and searched how they are used and what the advantages are.

And then I recalled: hell, I am a knifemaker, why don’t I design and make myself a leather knife. So I put some design on paper. I wanted a sharp point on one end of the blade and a circular part of the blade to do rolling cuts and a part of the blade should be suitable for pulling cuts.

Most important would be that this knife is stupid sharp so it would be as good cutting leather as my scalpel does.

I had so much success with my knife projects so far and not so many failures, that I completely underestimated how hard it is to grind the bevels of such a complicated blade. I guess it is not impossible but this knife is no beauty after all. I ended up doing a convex grind for primary and secondary bevel as this helps even out the grinding mistakes. It is difficult to have a consistent angle all around the edge and even harder not to grind into other parts of the blade while concentrating on another. So I consider this grind as my first real failure in regards to beauty. Sharpening went just fine and I have a razor-sharp edge.

I chose some beech wood for the handle, which I had sawn and dried some time ago. The wood is sufficiently hard and cheap for a prototype tool. I glued the Wood directly to the steel without any micarta liners – something I did never do before, too. But in the end, it looks like a useable tool knife and the first cutting tests are very promising.

I like the forms and styles that have a character. I like designs that are remembered. I like unique blade designs that give new opportunities. I am still developing my own personal style but some things drive me when designing a new knife.

The blades

Even the most meticulously made blades I make should be practical to use and durable. I am not making “Show-Only” knives that only look good hanging at the wall. I like recurved designs and blades with lots of character. I like doing crossover designs that combine two well-known styles into something new or combine old and modern styles. I like the blade to have a weight and when in doubt I tend to use thicker steel. Currently, I am addicted to carbon steel and love the knives getting character and develop a patina, a personality. I love tools and knives that have to be cared for like a gun, cleaned and oiled. It is like getting into a relationship with a knife as a companion.

The handles

The handles must feel ergonomic and comfy in the owner’s hand. Soft to the touch but robust hand tough when in heavy use. But he still should feel the knife, the weight and the capabilities of the blade. I want the handle to give a level of safety and confidence to the owner. The form should always serve a purpose. The thick heels of many of my knife handles give a good feeling that you have a secure grip while hacking with the blade or doing pulling cuts. Finger guards save the owner from slipping into the sharp edge. The form even should provide good handling when just picking the knife up with two fingers.

The sheaths

What applies to blades and handles also applies to the sheaths. They serve a purpose and that is a practical one. They are not only for show, but they should also be practical. They should protect the owner from cutting himself and most of all should be perfect for carrying the knife. I also like to go new ways of designing my sheaths to suit my knife designs perfectly. I like using thicker leather to have a robust product with years and years of use for the owner. I treat the sheaths with dye and a leather fat normally used for outdoor boots to protect the leather.

As the above is important to me I also added it to my About page.

I made the Kengata Santoku Chefs Knife for my mother this year and later a Petty Knife for her birthday too. She loves the knives because they are handy and extremely sharp. She handles them with much care and oils them after every use. But she had no good place to store them.

So my father made her a primitive knife sheath out of some scrap leather he had lying around. He just folded it around the spine of the blade and roughly sewed it shut with a thick nylon thread below the edge. I just finished my third knife sheath but sorry dad, this thing looked like crap 😉

My first impulse was to make two more leather sheaths but hey, these are Japanese style kitchen knives and did I do a Saya yet? No? So it was about time!

A Saya (the Japanese word for Scabbard) is a wooden knife (or better sword) sheath that I had seen made for kitchen knives too. So my chance to try out making one (or two) had come.

I wanted to start from real basic and cut the wood out of some piece of firewood I keep in my garage for our oven. I also decided to do Sayas for both knives, the Kengata Santoku, and the Furutsu. So I cut two thick boards.

Each Board I cut in three layers with the outer of equal thickness and the inner as thin as possible, about 0,5 cm. On the inner board, I drew the outline of the blade and cut this out. So I had a wooden frame that fits exactly around the blade of the knife. This frame I glued to one side of the other boards again. Before I used the frame as a stencil to draw the shape of the blade on top of the board that would be a side element. The outline would be needed later.

After the glue had dried I put a strong neodymium magnet in at the tip of where the blade would end and then I cut away some millimeters of the thickness of the frame on the band saw before I used the belt grinder to thin down the frame close to the 2 millimeters of the blade thickness. I drilled a 5-millimeter hole through one side. After I evened out the frame side and the remaining board I glued them together as well.

As I had the outline of the frame on one side of the glued up sandwich I added about a cm to the outline and cut that out on the bandsaw. The rest was grinding everything in shape on the belt grinder.

Just when grinding the Sayas to a finer grain I noticed that I accidentally used two different types of wood.

After doing all the leatherwork for the knives of my friends and family and having my Bowie Knife on my table in front of me I felt it was about time to do something for my knife too.

These projects I do for myself are the best chance to try out more things and take higher risks just because if I fail it is just my decision if I am happy with the result anyway or if I have to start over and have all the time for doing so.

I don’t want to dive too deep in the steps of making the sheath, as they are the same as on the other knives before. Most complicated about this type of sheaths I make is the order of the steps – when to dye, when to stitch what, when to glue and when to polish. I lately got a routine so I do not have to overthink the whole process every time.

I wanted to try out doing some leather carving where precision really counts just to check the limits. As this would be a sheath for my knife I chose my initials “AB” for the front and some leather punches for the back.

The biggest failure on this project was, that the secondary strap, that closes the open part of the sheath at the spine of the blade, was on the wrong side of the body of the sheath. I just made a mistake while designing the form and cutting it out mirrored. I have made a virtue of necessity and cut it off in favor of a separate strap that I sewed on the back of the sheath together with the belt loop.

As I said on the last post about the sheath for the knife of my brother I liked the result of the decorative stitching and on this new project wanted to take it a step further. I lined every strap and the belt loop with a stitching line that only serves for decorative purposes. What I also wanted to try was using a really white thread to put more contrast on the sheath between the black dye and white stitching. And yes I wanted to dye the sheath black like on the Kukri III.

I liked making my Chefs Knife, the Kengata, that is heavily in use in the kitchen of my mother. I talked to her about it and how it performs and she likes its shape, the ergonomy of the handle and the superior sharpness of the blade But for some tasks the Santoku Knife style is a bit too large. Now it was her birthday, so guess what, I made a small Petty Knife.

I chose the same shape as the Kengata Santoku Chefs Knife and scaled it down to the size of a Petty Knife. I chose a 2 mm thin 01 Tool Steel for the knife as for its bigger brother.

The most difficult part was finding the correct name for this knife. I did a lot of research but was not sure what these knives might be called. Finally, it was solved by #followerpower as the Instagramer @customchopshop brought up, that these knives are called “fruit” knives in Japan. So I decided to call this blade “Furutsu”.

The whole conversation is in the comments of this post:

This was the first knife I ground from start to finish on my 2 x 72″ belt grinder. That thing is simply insane, so much power and fun to shred steel on. No wonder the grinder is the heart of a knife makers workshop. The thing is so powerful that it eats away steel so fast that it is much easier to wreck a blade just because you touch the belt with the blade the wrong way just for the blink of an eye.

For the handle, I chose Ziricote again. I did not like the wood too much on the Santoku, just because it is so hard to work into form. It seems to clog up the grinding belts very fast. But as it should suit the Santoku Knife I went for Ziricote again. And I have to admit it is a very beautiful wood.

I just finished my tenth knife and it is here in front of me on my desk together with its polished leather sheath. I started making knives last year in October 2018. For my birthday I got my little belt grinder where I did all ten knives on. I tried out my first knife shape, that I quickly drew on a piece of aluminum, just to get a feeling. This was the birth of my first knife that I know call the Signature blade, my EDC.

I think it is a good time to take a quick look over my shoulder and summarize what happened so far.

The journey and pace is breathtaking on one side and slow and relaxing on the other Side

I learned an insane amount of techniques: cutting steel to the desired shape, hardening and heat-treating it, full and hidden tang constructions, making guards and sub hilt style handles, laminating my own paper micarta, working with expensive woods, glueing everything tightly together, surface finishes of the blades and the handles, making my own handle scales out of wood I salvaged in our garden, leatherworking, saddle-stitching, edge burnishing, and so much more in the details and how to do these things correctly. That is breathtaking and there is so much more to learn.

What was breathtaking too is the work together with my friend and first customer Joe from the US. He helped me push the borders of what I can do and push myself harder to get a better and professional result out of my work. Perfect is just good enough for me. Thank you for that and all your support Joe.

The first ten knives were just a start. The good news is: I get more and more inquiries about custom knives. I am very happy about this and it is an indication that the knives I make are good. Unfortunately what I also learned from that is, that the people have no idea what it means to put 20 or more hours into a single handmade product. Some are really astonished when we start talking about prices. Not bearing in mind I have to pay for materials, tools, and machines and till then I did not even earn any money.

And then there is the slow and relaxing part of knifemaking. Designing blades, putting them in steel, hardening, hand sanding, handle sculpting and finally having a finished product in hand to admire – that is satisfying and a relief. That’s why I don’t let anyone rush me. That is what I love so much.

Another awesome part of this work is the knife community all over the world. I am especially active on my Instagram account and the support and help, the appreciation, the communication with similarly interested people all over the world is a great experience.

My main goal is to keep the passion I feel for what I am doing. To find the perfect balance between pushing myself and enjoying my time.

I am planning to split up my work in the future in two different ways of making business:

• My main part of work will be building knives and trying out new things as they cross my path and putting the knives on stock/display.
• The other part will be fully customized knives where the buyer has the option to influence every detail – as far as technically possible for me. This

I’m planning a third way – so far just an idea in my head. If I have come to a conclusion, I will publish it here. So stay tuned I like the idea.

I did a sheath for the Bowie and one for the Hunter, the two knives I made as a Christmas gift for my brother and my father. I used a very thin, sloppy and colored chrome tan leather for them. The next sheath I made was for the JAMZT53 knife. This was also the first time I got the right leather (veg-tan) and did some leather carving and punching to give the sheath a nice looking surface.

Now I just finished the Kukri III and wanted to make a sheath that suits the quality of the knife of my customer and friend Joe. The last time I bought a pretty small piece of leather where the needed sheath parts fit barely on to. Now I looked for a supplier of bigger leather pieces to work with and I found one pretty close to where I live. They are a supplier of professional saddlery stuff. I ordered one square meter and a tube of leather glue.

Unfortunately, the delivery service went pretty rough with my package so that the tube of glue was damaged and some glue spilled into the package. Fortunately, the leather was not affected. But the tube was damaged. I wrote the supplier an E-Mail. Professional as they are I promptly got send a new tube of glue and a kind E-Mail where they said sorry.

The main problem with sheaths for Kukri knives is that the blade is wider at the tip, so I needed to make a form where the blade would slide in easily but would stay in the sheath safely when carried on the belt. I did a similar form for the Bowie of my brother.

The second important thing to think about ist what to make in which order. If you don’t think that to the end, then you can not fasten for example the push buttons later.

But first I had to do the leather punching. I tried all the steps out by making a little sheath for my first “Signature” knife. I just wanted to make a little different pattern for the Kukri and the sheath would also get dyed black to suit the ebony wood handle.

One thing I learned from the little test sheath was: Put tape on the back of the leather before making the leather wet and punching it. This prevents the leather from stretching. A tip I found in one of the plethoras of YouTube Vids I watched about leather works. I did not do this on the little sheath and It stretched about 2 centimeters (!!!) in one direction.

The second thing I learned: leather dye works great – on hands too. You just have a look at it and everything is stained – and it soaks through sponges in no time. Latex gloves solved the problem. Same for the glue, it is working amazingly. Fortunately, the dye and the glue dry very fast when working with them.

Before stitching anything I glued the leather together and the bonding is very tough. The stitching ads some stability and looks great. I decided to go with accented stitching lines and chose a light color for the thread. I bought a set of hole punches but they won’t work through three layers of this thick leather – so I just used them to mark the holes and used my mini drill to put in the holes one by one.

Another tough task was to fit the push buttons. They are not made for such a thick leather and so I needed to thin the leather down at the spots where I wanted them. I hammered a number of them and they got crooked before I had the right thickness of leather.

I bought some more tools like a stitching pony and an edge-beveler. The first one really helps as a third hand while stitching and the second one makes smooth rounded corners that later help when burnishing the leather edges.

The sheath has a folded part at the top of the wide part of the blade. The little sheath I did first also was folded instead of two parts stitched on top of each other. There I found out that I need to add a bit of space between the front and the back half, as the folding of the thick leather needs a bit of extra material. So I took that into account for the Kukri. That did work better but was still a bit tight. The knife now fits in like into a glove and if the leather stretches over time it will still hold the blade securely. Next time I will add some millimeters extra though.

I watched some tutorials on how to do a correct saddle stitch, not hard to do but it adds some extra durability and it looks so clean. Finally, all came together and I cut the leather straps to the correct length. I burnished all the edges that came together in the last step and treated them with beeswax. Last I treated the whole sheath with fine leather fat and I polished it. So the black color came out even better.

I posted some pictures on my Instagram account @simplyknives and my friend Joe, who I made the knife for, was very happy with the result. That is when all the hard work pays off when you hear and feel the excitement that results out of every minute that is spent into that piece of steel, wood, and leather.
