Introduction: Sheath Knife
make a genuinely usable sheath knife from stuff you probably have around the house, with a veneered handle, in less than 2 hours.
Step 1: Get Yer Stuff
I'm guessing this will take a about 2 hrs to make. it's a compromise between the rough and ready 'toolles butterknife blade' and the polished lovelyness of 'basta's blade.
your gonna need;
A butterknife, thats good quality - the width of the blade should taper towards the end, and be quite thick.
about a foot of 1"x1/6" ish hardwood stock. I used jetoba, which is pretty, but anythng will do
some good, fast drying glue. i used '5 minute polyurethane'
*optional is a bit of thin veneer(?)y stuff in a contrasting colour to you handle
tools n things;
A dremel, essential (unless you have a lot of files and and a months worth of patience)
with a grinder bit, a cut off wheel, a polishing wheel and a sander thingy.
a fretsaw (you could use a hacksaw)
an old sock
a gas cooker
umm. and some goggle. bits of metal in your eyes is not fun. casualty and a sadistic nurse with tweezers will await you.
Step 2: Blade Blank. Yay!
soo. as you saw in the first step, you'll want to draw on your design on the knife. have a look some knives on the internet for ideas, try to keep it functional, as with your butterknife you dont have much metal to play with. you will need to mark it very clearly, for grind. i found it useful to colour in the bits you will grind with a black marker, to get a sense of the shape. then grind away! you will probably want to use a cut off wheel for the tip, as there is a lot to grind away. be careful not to scuff the blade too much.
after that, get some wet and dry sandpaper and make the cutting edge smoother and sharper, then go over the whole blade, and polish it, because once it's hardened, thats it it. so make it nice and shiny.
jeez, these images are slow to upload.
Step 3: Sharpifying!
here's were it becomes a knife :D
start by marking out the area you want to grind the edge to (i drew a line around 5 mm in from the edge of the blade, but change that according to your design). then, erm grind it. in both sides. be careful not to scuff the main blade too much, because you'll hate yourself later.
Step 4: Hardifying
you'll need a sock, a pint glass and a hob. fun fun fun.
wrap the handle of the knife in the sock, and have your pint glass of water ready. turn on the gas, and start heating the blade of the knife, moving over the piddly flame to get a slightly even heating. do this till the whole thing is a nice cherry red, or close enough, then quench it in the water, putting it in tip first, prependicular to the water, to prevent any warping. you're blade should now the hard, sharp, and a nice orangey colour. yay.
Step 5: Handle!
this is probably the most difficult bit. i know. that easy? yay!
take your bit of hardwood and cut it in half. then, on each half, draw around the the handle of the blade knife, from the top of the wood. make sure these line up. on each piece.
then, you dremel out the shape of the the ex-butterknife handle in each bit of wood, so when put together, the handle fits nice and snug. (if your putting the veneer(?) in, you sould make it so the slots are slightly too shallow). *ignore this if you are not putting in the veneer* take your strip of wood, and apply your glue to itput the veneer ontop of this (it doesnt have to be neat, just bigger than the hardwood
put this delicious sandwich in your vice until the glue is dry. then, dremel out the veneer so you have the little slotty thing agin. now the two pieces, with the knife inside should fit together good and snug. yummmy.
Step 6: Shaping the Handlingingingle
this bit's pretty self explanatory. grab the sanidng bit on your dremel, and shape the handle to your specifications. you will need to cut the bits of veneer off the side of handle quite carefully, incase they snap and take a chunk out of the laminated bits. when you have done this, grab your danish oil, and rubit in with your trusty sock. give it at least six coats, which should only take you five mins or so, as it doeasnt really need to dry.
give everything a last buff, and their you go. one beautius knife, perfect for cutting vegetables, or skinning rabbits, or whatever. it holds it's edge quite well, and should sharpen on a good stone fairly easily when needed.
