Introducing: the Little Bugger

New page set up (very quickly) for my new gadget: the Little Bugger.

It looks like this:



They each measure from 80 mm to 90 mm long, are 3 mm thick, and are made from stainless steel (so your beer shouldn't mark them ). They are all individually numbered too.

Rough and ready, and they are indeed 'tough little buggers', hence their name. Caveat emptor, they are all slightly different, and have little blemishes, though I prefer to think of it as character, and it keeps the price down to a reasonable €20 (which as I type this is about £17.50 / $28.30), and includes postage, paypal fees, jiffy bags and the 5 mile walk to the post office

They're cute and chunky, and they open beers (I have tested extensively this fact ) and well, that's it.
Several have already been sold.

Here are another two knives out of the fire that I made from an old meat cleaver:

This was a small one I made for Valentina:



And this one is a bigger, woodland style knife for me:

The knife-making is continuing, though I've not done anything else recently apart from work, work, get sick, work, get sick, and more work.
So here's some pictures... As usual, clicking on them will get you a big looksee.




The first one is still the experiment piece, and now I've put a handle on it.
Here are a few more.





This one is made from an old file, it needs cleaning up, and then quenching and treating.









This one a fave, I like the form, it's very sharp, and it has a bottle opener...


this last one is still being made...





And this one will be very serious indeed, it's big and heavy, so I've drilled out the tang, which'll be hidden in the handle.

 

Making a Knife

I don't think this can really enter into that elite group known as "knives", but it's my first, so here goes:

No sniggering at the back...

Making a Sharp Pointy Thing

So after reading many, many pages of useful information, and only feeling ever so slightly in awe of the whole process, I took the plunge and made a “knife”. I have an old file, ready for the first real attempt, but a stroll by a train line produced a small piece of very rusty metal. I decided that this piece of metal would do as a first go. It's probably not the right kind of metal, it's rather soft, it's too thin, but it was free, and I can see just how difficult it is, I can have some fun, and even if the result is worthless, I can perhaps use it as a template, or just a lesson in how not to do it. So I did it.

This is the piece of metal, very rusty, pitted and slightly too thin.



I sketched out a knife shape (roughly based on a scuba knife), and then I drew this on the metal.



With a hacksaw I cut out the knife, resorting to using the angle grinder after the blade snapped (even the slightest twisting movement can break a saw blade just like that, you see, one lesson has been learnt already).



Then I used the angle grinder to round some edges. Yeah, it gets the metal too hot, but this is a test scrap, so I wasn't too worried.



At this stage I was planning a knife with a cord handle, but then I got carried away with the file work and made finger indents to go with the grooves on top of the spine for a thumb grip.



I went from the file to sandpaper to clean up the knife as much as I could. Being so thin I couldn't really do much about making a bezel (what should I have done here?) as it started to make a sharp cutting edge, something I suspected would be a problem later when I'd put the knife in the fire.



Spot Siku, my husky, wondering what I was doing...





So with a very slight bezel, finger grooves and just two holes in the handle, I started up the bbq and when I had the charcoal, I put the knife in the middle and waited.

Working on the theory of getting it cherry-red-hot, and waiting till the blade no longer stuck to my second trusty magnet (my dog nicked the first one), I had a tin of vegetable oil ready for the quench (which I heated up by stirring it with a red hot poker every couple of minutes till I dunked my knife in).

When it stopped fizzing and smoking I put the knife in some water, and then ran a file over the edge to see if it had hardened. It felt a bit harder than before, but then I did the whole heating process again for luck. I guess I didn't have the nerve to decide it was ready.

Then I cleaned up the knife (but with it was still smelling of chips, the oil was recycled), wrapped it in tin foil, and put it in my pre-heated oven – set at 190° C. After an hour of that I let it cool down with the oven door open, and then I started over on the sandpapering, first coarse stuff, then finer and finer.



The knife is marked and has some pitting, but it's just an old piece of metal, so I like it the way it is. It has a brutal character that appeals to me.



After cleaning it up just a bit, I worked on the edge with some sandpaper and then a sharpening stone. It can cut paper, and it can cut logs, so I'm chuffed.

Now what? When I find some cord, I'll see about making a handle with that, but the finger grooves will make life difficult. With the two big holes I'm not sure how to go about making a wood handle or similar.



I have some thinnish leather lying around, so I might try to make a sheath for it. I guess that's the spirit of this sharp pointy thing: made with what I found or had lying around.
