Custom


Making a knife doesn’t mean you have to start with a lawn mower blade and a forge.  A variety of steels in terms of grade and types are available.  Also available are knife kits which in which the blade is  pre-shaped and sharpened.  These kits also come in a variety of completion.  Some have all the components and you assemble your knife. Other require a little more effort on your part.

Woodcraft offers a variety of learning projects so I signed up for the knife making.  I wanted to see how they handled epoxying and pinning handles.  As you’ve seen on Forged In Fire, pinning handles onto your knife is one of the major stumbling blocks for contestants.  They need to drill through steel, align holes, hammer pin in place while the five minute epoxy is hardening.

Basic kit plus wood handles

Here’s my kit and I’m using a light olive wood for the handle.  The first step is to turn a 3/8 inch thick slab into two slabs.  The second is to tape your blade with removable painters tape.  Use lots of tape to protect your hands from the edge.  Safety first.

Turning one piece of wood into two

We traced the handle on the wood blanks making sure a square end of the wood are in  complete contact with the bolster, then on to the band saw.  Removing excess wood is a time saver, but leave enough just in case your handle needs to be finessed a little.  But really, a hand coping saw would have worked just as well.  You could just sand it all away too.

After you assure yourself each side of the knife’s handle has the correct cutout, the pins fit correctly and you’re happy with everything, dry fit it together again.  Can’t be too careful!

Clamped

Now get the clamps out and mix your epoxy.  So, Bunkie, five or thirty minute epoxy?  The class used five minute because it is fast and we gave it a half hour.  I like the thirty minute or longer.  I want the longer time for fixing an “Oops!” and I believe longer cure epoxy is stronger.  While I have no plan to destroy an elk’s skull or batter the hood of a 1948 Ford pick-up truck with my knife, stronger always seems better to me.

After the epoxy is cured, it is sanding time.  Woodcraft has a variety of terrific sanders, rotary oscillators with different radius, belt sanders, disk sanders but all you really need is any sander you have and patience.

Sanding in process.
Your plan of attack is different from anyone else.  I like a rounded handle with a palm swell and flat top.  Start removing wood, but remember the Golden Rule of carpentry:  It’s easy to take wood off, very hard to put wood back.

Keep handling your knife.  How does it feel to you?  Too thick?  Too rough?  Edges sticking up?  Keep working.  And while you’re striving to make your knife, remember perfection is the enemy of accomplishment.  Experiment with it.  Do you want an asymmetric “D” shape handle or maybe oval facets?

Finished


When you get it to the shape you want, move to a finer grit paper.  Work your way down to a finish you want.  How about polishing to a 4000 grit finish?  The wood starts to come alive the more sanding dust you create.

The wood finally explodes to life with a finish.  You can stain it, wax it, linseed oil it, urethane it.  That’s up to you.  I used a coating of flax seed oil.  Just a fancy name for linseed.  That a drying oil, so I left it outside in the sun to help cross link the finish.

It’s not perfect, but the next one I make will be better.  I know what to look for and what to watch for.  And I know how much fun it was.

Did you drill the holes in the steel of the knife handle?

No, the holes were already pre-drilled. One of my fellow classmates didn't understand the pins were larger than pre-drill hole and the instructor had reamed two of them out to fit the pins. This fellow drilled his wood for three holes instead of two. So we stopped class while the instructor enlarged the middle hole.

So yes you can drill holes in the steel handle if you want to put your pins in different places.
