As part of a swap, I generally build a test item, similar to what I’m going to send off for the swap. For the 2017 knife swap , I planned to make marking knives, and this is my first test knife.

I was working with a ¼” marking knife blade from Ron Hock, so I needed to prep some ¼” thick stock. I ripped a piece off the edge of a ¾” cherry board I had, and also a smaller piece of ash. Then I planed it square and flat. That’s a LN#2 smoother for scale in the second picture.

A little work with the saws to rough in the shape, and two glue-ups later, I had what you see in picture 3. I left a lot of the blade protruding as I plan to use this for marking dovetails, and I want to be able to reach into the bottoms without running out of blade.

The fourth picture shows me fine-tuning the fit. I used a .308 cartridge as a ferrule (visible in the background), so I needed to round things off for that. I then planed the handle octagonal, knocking down the corners by eye.

Then I topped that with a piece of .50BMG cartridge. Once all of that glue had set, I smoothed things off with files and sandpaper. Picture 5 shows it rough. I would end up filling the gaps with CA glue and sanding some more to get what you see in the first picture.

Finally, it got three or four coats of orange shellac. I sanded between the coats with 600, 1000, and 1200 grit wet-dry sandpaper. And that’s picture six.

I find myself using this pretty often in the shop, and once my recipient reveals the one he got from me, I’ll post the second version which had a few tweaks I made after seeing how this one worked.

Thanks, Kenny. It was definitely a practice effort, and I learned a bunch along the way. just knowing what order to use the various hand tools in to keep things efficient makes a huge difference.

That is a cool knife. I like the shell as a ferrule, gives it a manly look. You pulled the trigger on this one.

Thanks, Dave and Jeff! I was pretty happy with the shell as a ferrule idea. I hadn’t seen that before, though I have a friend who turned me a pen that used a shell and a fake bullet as the tip. I gave it a try, and it turned out pretty good. I was initially thinking I was going to use the base of the cartridge as a cap on the end of the knife, but I couldn’t figure a way to make that look right.

The thing I find with building “one for myself to practice one” is that I always find a few things to do better for the one for the swap, so I think I’ll keep working that way. And then once it’s built, I always find something new to screw up, too. :-/ Hopefully I can get better on that part.

Just be aware that if you want to use a shell casing for a ¾” knife, you’ll need a 20 mm shell, and them ain’t cheap.
