It started out with this crappy old monkey wrench. No good for wrench-type activities anymore.

"My bored boy-mind saw some ready-made knife like features in the design that I wanted to keep- the adjustable lower grip was already a guard, there was already a fuller groove, and those little teeth were already half way to becoming serrations. The twirly adjusting thing (i don't know wrench-anatomy) would make a pretty cool feature and serve as a finger grip."

"I fired up my forge, which is called Dolores. Yes, it's a bin lid on a wheelbarrow with some cement and an inflatable mattress pump. And it works!!!"

"Started shaping out the head into the tip of my knife. Because it was so sunny, it was really hard to tell how hot the blade was. I ended up having to pull my apron over my head and checking out what colour the blade glowed in the shadow, and it's really hard to take photographs when you're doing that. As it's a coal forge, I get a really good heat on there and it's actually pretty easy to overheat if I'm not being careful."

"After a some hammering, the blade is complete! It was a challenge to forge around the moving grip whilst keeping it intact, which is why the shoulder of the blade suddenly scrunches in. Once the width of the blade was drawn out, it stopped the lower grip from being able to move, although it still rattled a bit."

"Rough grinding the blade to shape on the belt sander. Shortly after, I welded a few spots between the blade and grip-guard to stop it rattling."

"After a rough shaping, the blade has been heated to an orangey yellow colour and quenched in oil to harden, and then oiled, wrapped in tinfoil and tempered in the oven at 220°C (That's about 425°F to you imperial scoundrels) til it became sexy like a sapphire storm cloud."

"The handle did have some lettering stamped on it that might have made a cool feature, but it was quite worn and i thought that the lower grip was enough, so I added some oak scales with two pins, and set with epoxy, While that was happening, I profiled the serrated teeth with a needle file and did a bit of light sanding."

"All set! I also put in a very rough lanyard hole that i'll probably round out when I get the proper tools. Next the whole piece needs to be sanded, polished and oiled."

"The finished piece! The guard is solid, but the twisty thingamybob still moves a little, which I like- It's like a fidget stabber."

This is the result. Cool, huh?
