I'm posting this because of the new mule teams coming out and guys not knowing where to go to find handles that fit well. I was there at one time. It's frustrating. I finally got sick of some of my favorite knives that had handles that didn't feel right or, like the mule team, didn't have scales at all. So I set out to make something for myself. Eventually I'll move to some sheaths too, but right now I'm trying to get handle making work well. I'm still at the baby stages but that's all you need to make some really good handles and once you see how easy it is you'll start wondering about what else you can do with knives. I'll start with a list of everything I need to make a basic set of functional scales for a knife. I'll focus on the mule blades. Now, I'm by no means an expert. I've only done one complete knife and am working on my second now. It's so easy, though, that the results should be easy enough for most people to get something nice if they put in a little elbow grease.

Halpern scales are nice but they don't fit the best.

Go to woodcrafters, they have a lot of what you need. You can also go someplace online like Texas knife supply but they have higher end stuff that's more expensive than what I saw at woodcrafters. Online places also have G10 and bushings if that's what you want to use instead of wood and pins. If you want to go really fancy places like bad dogs burl source has some really, really nice knife scales and you can choose the exact pieces you want.

Harbor freight has a bunch of stuff you need on the cheap. Starting out you don't need much.

So to start:

Cheap scales in good wood. You can buy a set of precut scales for like 5 bucks. Buy a couple in case you mess up.

Buy some 3/16 pins or bushings. That's the size of the holes in the mule team. They're pretty common. You can get brass, stainless, or nickel pins.

A belt sander. I just picked up a 1"x30" at harbor freight for about 30 bucks. They come with an 80 grit belt. You can use that and only that as a belt to start. It'll last a little while unless you're grinding a bunch of metal. If you want better belts or a good selection you'll have to find someplace online or whatever. I havent needed them yet so I haven't looked too much. Once you see what this little thing can do you'll start thinking about regrinding blades and making handles for your other knives.

Buy some sandpaper sheets from 60 grit up to however high you feel like going. Woodcrafters only had up to about 1200 grit.

Some good epoxy. Ask the guys at woodcrafters. They'll point you in the right direction.

If you want to die the epoxy some color then buy the pigment too. I bought some black pigment and it works great so far.

You need a drill and 3/16 drill bit. You can buy a used one from a pawn shop on the cheap. Just buy some good bits, they'll make your life easier.

A thin file to saw the pins.

Buy two decent clamps, they cost about 3 bucks at harbor freight.

A hammer to peen the pins if you want. You don't really need to do this if you're using epoxy but you can if you want.

A pen, pencil, or marker.

Something to mix the epoxy in and with. You can use a bottle cap and some toothpicks. No big deal.

A set of pliers to manipulate the pin once it's in the hole. Unless you're using a drill press the hole angles on the scales will probably be off just a little and the pin can get stuck. Not a huge deal.

Some place to keep the stuff. The only thing you probably want to go outside for is when you're using the grinder, sanding, or drilling. Everything else can be done at your kitchen table.

________________________

So get the knife blank. Figure out which specific piece you want. Align the grain how you want. Trace the pattern of the knife on each scale. I draw it on the presentation side of the piece.

Clamp the blade to the piece of wood and drill out the pin holes. Try to keep it at a right angle. You don't need to be perfect but you need to be close. Start to drill from the presentation side because the wood will probably crack a little on the side where the drill bit exits. Keep that hidden on the inside of the scale. You can sand out the small torn out parts out of the scale but you may take too much off doing that. Repeat the step for the other scale. Now you have two blocks of wood with the knife outline drawn on it with the pin holes already drilled.

Now cut the pins. It'll take a couple of minutes to file or saw through them. Cut them a little bigger than you think you'll need. You can grind them down later very easily.

Now line up the blank and to blocks of wood. Put the pin in so you can see if you need to wallow out either hole at all. Once your pins fit pretty tight but not too tight, remove the blade so both blocks are held together with just the pins.

Go to your sander and sand down almost but not all the way to the outline you drew. Both scales should be pretty even around the outside and you'll start to see the makings of your knife handles. It'll take about an hour's worth of work up til this point, not including the supply run.

Remove the pins and rough out how you want the handle to be shaped. If you want flat, then make it flat. If you want it rounded, make it rounded. You can rough out a palm swell. It's easy and takes about 20-30 minutes at the most. Just remember to go slow. You can always take off but once it's gone, it's gone. Take time to compare both sides. Keep the rough out pretty even on both sides. You'll have to eyeball a lot.

Don't mess with the inside of the scales too much. You want them as straight as possible. Unless you have a steady hand and a good straight edge, leave them be. You do need to make a quick pass across the belt to rough up the surfaces but don't take anything off.

Now go in and wash the scales and knife blank. Remove any dust, oil, or anything. Try not to touch the tang too much after you wash it. Let them all dry.

Now go mix your epoxy. If you bought quick setting epoxy then you need to move fast. The stuff I have I can mess around with for about 45 minutes before needing to leave it alone to cure.

Have what you need to mix and apply the epoxy in front of you. Also have the pins, scales, blade, clamps, and hammer in front of you. Have several rags or paper towels, too. Lay some newspaper down on your table to catch drips and so you can lay the stuff down .

Take the epoxy and smear it all over the inside of each scale. Push a little extra into the pin holes. You don't need a ton of the stuff but you want just a little bit to squeeze out when you clamp it.

Now push the pins into one of the scales. Put the knife blank onto the pins. Put the other scale on.

Clamp all of the stuff together. Wipe off the epoxy coming out just to keep things a little neat. Don't worry about getting epoxy on anything on the outside, it's going to be sanded off anyway. Set the clamped up knife on something and let it sit overnight.

Heres mine curing right now. It's a single pin. I could've had a lot more but with this knife it'd be purely for aesthetics.

Notice the extra epoxy and long ass pin? I made a mistake on my first knife and this is me making up for it.

The next day take the clamps off. Now you have a rough knife. Go sand it down to its final shape. Whatever you feel comfortable with. Thin, fat, round, or square. Your pins should be as easy to sand down with the belt sander as the wood. Remember to go slow.

Now that you have a knife with the handle shaped how you want it, take the sandpaper sheets and remove the belt marks. 80 grit belts leave a fairly nasty looking finish after I'm done removing the scratches using the sheets, it looks nice. This is the most time consuming part, hand sanding it. It'll take at least an hour to just get the belt's scratches out, depending on how hard the wood is.

Once that's done you're pretty much set. Take some gunstock oil or similar and smear it on. You have yourself a knife with handles made by you for you. Total time to work it is maybe 3 hours, and that's pushing it. Letting it cure takes 12 to 24 hours, that gives you time to come onto the forums and share just how easy it is. The total cost? About $150 to buy what you need. For the knife specifically? Well, if you spend $5 on the scales, then about 8 bucks. Most of the stuff you can use for other things.

Hope this helps. You don't need much time, effort, tools, money, or experience. You just need a list of what you need (which I hope I helped with), a little bit of time, a little bit of patience, some simple know how, and an idea of what you want your knife to feel like.

When you're done you should have something close to this. It wasn't hard and I'm definitely no craftsman or anything.

I'll post the pics of the MT when it's done.

Oh, and for you experienced guys, please take it easy on me :)


I went just a little too thin right at the front but it's still comfortable. I think it took me longer to write this up than to finish the knife after curing.

Just looking at adding scales to a fallkniven wm1 as well as a Mule in PSF, thank you for the writeup and inspiration. Great writeup.
 
Nice write up and job on the scales.

I was looking through pieces of wood for handle scales for the MT21 when I remembered a thread where someone used leather.
Well, why not. If it doesn't work out, no big deal, just cut'm off and use wood or micarta, like I usually do.
So I got some scrap leather and made them. Took about an hour, taking my time.
Nothing fancy, just functional. Had them on for about 3 weeks now.
Very comfortable so far. If they work out, I might do another one.

Why not just screw the scales on, like the originals?
Nice work, BTW.
 
Excellent post bodog. I was looking at the Harbor Freight 1x30 belst sander yesterday and was trying to come up with reasons why I need this machine in our garage. I just get the sense that a Mule Team Project is starting to take shape and I can't wait to see where this goes. Thanks.....
 
A couple of pointers since the first write up. Make sure the wood is stable. Either a hard oily wood or stabilized. I had to redo a knife because after I put the handles on they shrunk. The mule team blade in the first post wasn't finished very well. The spine was left at 80 grit finish from the belt that came with the grinder. I now have the appropriate belts but my wife uses that knife all the time and asked me not to tinker with it because she likes it as is. All the knives I do now have pretty polished tangs and spines.

Drill the holes through both scales at one time if you can, before grinding out the rough shape. It reduces the chance of misalignment. Either buy a drill press or make some kind of jig for a hand drill. Don't trust your own eye. Trust me, you'll mess up if you try to eyeball it. I got lucky the first two times and unlucky the second two times before I gave up and bought a drill press from harbor freight. Life is much easier now.

Finish the front part of the scales before you epoxy the scales on. Otherwise they'll need to be finished with regular paper and it'll scratch the ricasso no matter how careful you are.

Lay some 60 or 80 grit paper on something really flat and flatten the scales on the part that'll sit next to the tang. It'll look better than if you just trust how it comes from the saw when they were cut. Evenly distribute the weight over the entire scale or you'll wind up with a curved scale.

If you peen the pins, be really careful. You'll dent the scales if you miss or crack them if you hit the pin too hard. I don't try to peen them anymore, not without the appropriate tools. I also use carbon fiber rods. I think they look nice and are easier to work with. I'll likely use nickel silver pins in the future instead of stainless.

I've done probably 10 knives now. Some for me, the rest for some coworkers. I'm only charging the cost of materials and I tell them I'm just practicing. The guys I've done it for have thrown some extra money at me when they got their knives so I guess that means they were satisfied. I'd like to think I'm getting better with each one.

I'm about to get into hidden tang knives and removable scales but as of right now this is kind of a quick progression of what I've done. The mule team I posted was the first. Followed by the ZT which I had to redo even though I thought it turned out really nicely the first time. It disappointed me when I had to grind those original scales off but the ones on there now I don't think look too shabby.

Like I said, I'm definitely no craftsman.

Last word, if you're going to be heavily profiling the handles, buy some j weight belts. X and y weights are too stiff to look nice without being super careful and slow.

A little Dremel type tool is pretty helpful, too.

Man that's beautiful. What kind of wood was that? Burl?

The top two are buckeye burl and the other ones are spalted maple burl. I have some black locust burl I'm about to put on a small rex 121 blade, some more of the spalted maple on a bigger vanadis 10 blade, some black g10 on an m390 blade, and I haven't decided what im going to use on a beautiful vanadis 6 blade I have.

Thanks for the write up and the updates!
I've been looking for scales for my MT-18 as well and now i'm going to follow your lead and make them myself.

It'll be a bit as i'm in the process of moving, but i'll post when i'm done.

Thanks!
