Handle Treatment: What Do You Do, and Why?

We've had a few handle threads in recent days and it got me to thinking. I've spent the last year scouring the HI website, the archives here, and some other sources in my quest for the best/easiest/quickest/most efficient finish - not just for any particular material, but for all materials in general. I'm not there yet, but maybe you are.

When I first came here I could refurb a milsurp stock to as-new condition without much trouble...once you know the way it's supposed to be done it's actually very easy. It's not necessarily the most attractive way to do things though and, by and large, my handles looked like crap. I'm fortunate in that we have some very skilled woodchucks here who were willing to help me out.

We (as a forum) have improved our techniques for finishing handles in the little time that I've been here. We have some new members who may or may not be inclined to wade through all of the material from the past. (Some of which is obsolete.) There are some real woodworking experts here. With all this in mind, I ask that we offer up our collective wisdom and trade some notes, all in one place. It's about time, don't you think?

I'll start it off.

Upon receipt, every handle gets cleaned. I spray it down with engine degreaser (the foaming kind) and work the entire thing with a plastic small arms cleaning brush (think of a stiff tooth brush), paying particular attention to the red areas. When most of the junk is removed I switch to #0000 steel wool and mineral spirits. I wipe it dry and dunk it in mineral oil. It stays there from 1-3 complete days, depending on how patient I am. This goes for wood, horn, antler, stag, bone...anything but metal. (My one metal-handled khukuri is not particularly comfortable but it is easy to maintain.)

After the mineral oil soak, I clamp the blade in my vise (with the handle lower than the blade) and suspend it over my bucket of mineral oil. I let it sit for a few hours and wipe off whatever's left. It sits for a few days after that to "dry." It doesn't actually dry, but what's left near the surface seems to migrate inwards. When it's completely dry to the touch I proceed.

If the handle is wood, I go on to the "Walosi mix" as described by Dan Koster. I initially lay a heavy coat on; I lay another coat on again, especially in any dry spots, a half hour later or so. I let it soak for an hour or two and wipe off the residue. I'll do this once or twice. After that, it dries a day.

If the handle is horn, antler, stag or bone, I skip the Walosi mix.

Next, each handle gets hit with Watco Danish Oil. Again, it gets a heavy coat initially and sits for a few hours. I apply the oil with the blade partially in the scabbard to give me something to hold on to; I leave it sitting like this on a horizontal surface to keep the oil from running into the scabbard. (I could care less about it getting in the scabbard but it's a PITA to remove from the bolster and blade when it's dry.) I let it sit for a few hours, wipe it dry, and repeat the next day. Occasionally I'll wet sand with the Watco using #600 or #800 sandpaper. Later coats are lighter, but each is wiped completely dry after soaking for a bit. I do this three or four times. (Always at least four for horn, stag, antler, or bone.)

Finally, if I think that the handle warrants it, I'll build a coat of Tru Oil on it for that "looking through glass" effect. Light coat of Tru Oil, wet sand with #800 and water after it's dry, repeat. I go until I'm happy.

Now, here's my reasoning on all this: the mineral oil (as Dan says) is great because it's very inexpensive, doesn't go rancid, and most importantly to me, it doesn't dry. It also seems to penetrate well. I leave a bucket of it sitting next to my vise, uncovered, and handles can go in and out at my conveniance. The oil will always be fine. Any excess will run out instead of getting gummy and it fills the gaps between the bolster, handle, tang, and buttcap without making a mess.

The Walosi mix penetrates very well and isn't bothered by the mineral oil - whether it simply goes through it or takes it with it is not evident to me, but it gets in there and works. It gives some depth to the finish.

The Watco doesn't seem to go in so far but it's easy to find, relatively inexpensive, and doesn't gum up if you wipe it dry. (The Walosi mix gums up on occasion if I stop there. Walosi probably would've just sanded through it and kept going, but I lack the patience.) It also seals the handle very effectively and is easy to touch up.

The Tru Oil is just for looks. I'm not impressed with its durability and it can be slick when wet. I often skip this step but man, it looks good when done right.

Besides sealing the handle and bringing out the figure, I'm also looking for chatoyance (sp?) - I want the handle to appear transluscent, where I can look "through" it and see what's underneath. Chandan in particular reveals much when treated this way but even dead black horn can give up some details when it's soaked with enough oil.

I'm still experimenting with wipe-on poly and finishing wax. I'm not sold on either yet. (Although the finishing wax looks pretty good and is very durable in my experience.)

Pics available upon request. I'm in the process of finishing (and refinishing) a bunch of handles in preparation for winter, so I've got a variety of handle materials in various stages of completion sitting around right now.

If you have a method that works well for you, please, by all means share it. My way is not the right way - it's just my way.
 
Geez Dave that was great. Thanks for taking the time. Couple questions:

1. What does "Walosi Mix" consist of/Where can I find 411 on it?

2. You danish oil horn? Hadn't heard that before

3. Please send pics.


So far I've refinished all my handles. Started at the belt sander smoothing the exposed tang on Chiruwa knives. Then used a small file to get into the grooves. Then sanded the polish from the horn and finally just treated it with vitamin E oil. Pretty nice, but I think that mineral oil treatment would help.

I've been applying the tru oil finishing method found in the FAQ section on my Badune Special. Does anyone not like that method? Why?

Thanks again Dave.

Nothing but Ballistol®- and no cracks.

I've read how horn, saatistal and chandan crack just if you snap your fingers. Maybe it's my high humidity, but I've got over 2 doz. HI's of every make and not one crack in any handle- at all.

I stick to B-lube for two reasons- one, it works on wood, metal, horn & leather. Two, I'm lazy :foot: and don't have time. Also, lost all my linseed oil and accumulated wood finishes when the garage flooded.

But the crack thing- just never has happened. Miss Yangdu should move here. :D Or I could quit my day job and trans-ship everybody's khukuris.

Boiled Linseed oil for wood handled khuks, Hooflex for horn. I give the handles an application every couple of months and let them sit overnight before wiping the excess off. I forgot to do the last step a with some of my wooden handles and now they feel a bit gummy.

I've had good luck with spar varnish. When I first get a khuk, I give the handle a thorough scrubbing with a stiff plastic brush and mineral spirits to remove the rouge and waxy coating then let it dry out for a few days. Next the handle is lightly, but completely sanded down to fresh wood. Then I give the handle several coats of spar varnish that is cut in half with mineral spirits-the wood just sucks it off the brush! Be sure to give the handle a light rub with fine steel wool between coats!

I then finish the handle with 2-3 coats of uncut spar varnish. Depending on the knife and my mood, I will leave the gloss finish or rub it down to a nice satin with fine steel wool.

Spar varnish has several advantages in my opinion. This stuff is made for long term exterior exposure. It provides nearly bullet proof protection to the wood, it is designed to expand and contract with the wood over time-unlike a reguler polyurethane, and also offers UV protection.

Anyway, this has worked well for me.

I used spar varnish extensively when I worked on sailboats. If you ever live near the coast you can always find work on peoples boats. Mostly woodworking and refinishing is what I did. Sometimes though my father-in-law made me squeeze into the bilge and do the nastiest. Don't do that!!:barf: Spar varnish good! Anyone else use it on Khuks?

Gracias! I'll give that a try. Andy
 
I clean up the handle with a solvent - it could be Formby wax remover or mineral spirits. If I want a shiny finish or a matt finish - I usually start with 4 coats of Watco, much as you do.

If I want a shine on the final coat, I may sand first, or between coats. If I sand between coats of anything, it is with an artificial "steel wool" that is at least 0000. I often just remove the wax and then go at it.

The final finish depends on my interest in appearance or protection. The Watco is great for sealing the wood, and it prevents cracking in horn or minimizes shrinkage in wood. If I want a dull satin finish, I may either leave it alone or use a coat of Minwax dark furniture wax. If I use anything to buff horn, it is going to be the finest sanding paper I can find - like 1000-2000 grit.

Watco is my preferred finish for horn. I don't use anything else for horn.

If you follow Watco with poly or another finish, bue sure to let it dry first for at least 3 days.

I use it for wood. I can't see adding oil on top of Watco. Both are designed to go into the wood and penetrate it. Watco has oil and varnish. Oil is not a suitable surface finish.

I have followed Watco with a wiping varnish. Watco makes a poly, and it works. I just don't like the plastic feel of it. Formby makes something that they call a satin "Traditional Tung Oil Finish," but it is really a wiping varnish. It contains varnish and spirits and gives you a nice shine and surface coat - after the Watco. It will give good protection, but looks much nicer than polyurethane finishes. You just wipe it on, and make sure that the coat isn't too thick. Then let it dry 12 hours between coats. It is a varnish finish.
Give it a try - and use it after Watco. The Formby is available at Walmart, and a can lasts forever. It gives a nice shine. I use it for knives where I want a shiny coat.

Like Mike I use Ballistol and no problems, actually I'm the one who got everyone to using the Ballistol.:thumbup: ;) :D And like Mike says, "Good for wood, metal, horn & leather."
I really do need to order some and just keep putting it off.:rolleyes: :o
 
Yvsa, where do you get the ballistol?

This is the best place as far as I know right now. Some of the other guys may know of a better one but these folks seem to be very reasonable.;) :D
Ballistol.
 
Ballistol is not a bad choice at all. Most of the current batch of handles being finished have seen some Ballistol at one time or another. I look at it as something that I use on blades primarily but if it happens to get on the handle or scabbard, it's not a big deal. (In fact, it usually helps.) Once every six months or so each scabbard gets a few shots of Ballistol into the interior to kind of wet things down. I also use it extensively on the frogs to make them more pliable.

Come to think of it, I use it on the sheathes that I make as well. I tend to go rough side out these days and the Ballistol gives it a measure of water resistance without the mess of soaking in wax.

This latest batch of handles is getting Minwax Wipe-On Poly as an experiment. I gave each a very thin coat this morning. Currently (about eight hours later) most of them are still a bit tacky. I'll see how they are tomorrow.

Current experiment: I took a section of 1" oak dowel (the kind that I use on my cutting stand) and soaked it in mineral oil for 24 hours. My plans are to cut a section out, then repeat. I'm planning on doing this for two or three days to see how the longer soak times affect how far the oil penetrates. I'd meant to cut a section out this evening for inspection but this is my last day in the Navy, celebrations have commenced, lots of tequila is involved and I'm not feeling the power tools right now. I'll get that done tomorrow.

I haven't used spar varnish on a khukuri yet but I've used it on spear shafts with good results. That's an experiment for another day.

Good stuff, folks. I'll try to take some pics of all of this tomorrow. Tonight's not happening. :)
 
Is it absolutely necessary to refinish the handles on kukris, or would the finish that comes on the handles be enough to protect it from cracking?
 

welcome

Most of mine have not had any work done
& none I recall developed new cracks

it can depend on your local humidities
and it depends on the wood variety
& whether it was properly cured

recently I have started soaking each newly received khuk
in an oil/solvent penetrant
just to be sure
maybe

None of mine have been really 'finished'

The 'finish' applied at the factory is simply the wax left over
or left behind when the khuks are polished/buffed

Traditionally, no finish or treatment is common

btw,
some woodworkers depend only on wax
very commmon among woodturners

Unless cracking -does- become a real problem for me
I won't put much effort into prevention

As for myself I refinish wood period. I like doing it. I like building a finish and watching the depth come out of the wood like majic. I love when you build something in walnut (my favorite) and have it all sanded up and then first brush on the finish. Suddenly its dark and lovely. Theres grain and patterns and even colors that werent seen before.

I can't say one way or the other about the original finish on Khuk handles. Obviously there are much wiser people than I on this tipic. I just like re-finishing wood, and I want my Khuks to look dazzlingly great.

Shall I put a finish on neem though ? I guess if I do the wood's fragrance would be sealed ?

why not try neem oil?

supposedly inhibits wood decay and fungus attack, as well as killing termites. do a google search for online suppliers.

did note it supposedly has a repulsive smell similar to garlic, does the wood smell like that? also reccommended for human skin conditions, lice, excema & fungal infections. are you subject to athlete's hand (tinia manus)?

(p.s. - i haven't a clue what either the wood or oil smells like, or whether it would actually finish wood, so caveat emptor)
