Conventional portland cement based concrete isn't refractory and can be explosive due to off-gassing when exposed to excessive heat. I've heard a few stories of potter's kilns exploding because the concrete slab wasn't sufficiently insulated. There are refractory concretes out there, is this what you're using, Elias? I feel in the interest of safety this should be clarified. Edit: I meant to say, painting firebricks with a 50-50 mix of alumina hydrate and kaolin will help to reduce the fluxing action, but soft firebricks really don't stand a chance against flux.

I get the feeling the feature was turned off. I suspect because it uses data/bandwidth.

I really like the look of that second knife, though both are beautiful. Congrats on the elk. Also, kudos for donating the bear skull. My local trapper's council has a wildlife education program and its dependent on donated pelts, feathers, and bones to make the display work.

It's not illegal like, say, bootlegging dvd's is illegal. The FBI isn't going to bust down your door. But if the original designer catches wind you're selling unauthorized copies, he might decide to seek compensation. In which case, he doesn't even need to be right for you to be in a heap of trouble. In order to even deal with his claim against you, you'd have to hire a lawyer which is already going to cost you exponentially more than any knife is worth. If, however, you're just looking at other makers' designs to get an understand of the principles of folding knives (e.g. how a liner lock works), then you're fine. Nobody's got a copyright on the basic principles of how a folder works (unless it's a patented mechanism, or something), so you can use other's designs to learn from, but copying directly isn't a great idea.

A nice little knife, Hloh!

Congratulations, Mark!

Be a little careful with ash water, though. It weakens your fingernails and thins your skin.

Very elegant.

This is going to be an exciting project to watch. Awesome work so far, Dave!

I think it was just sand. Silica, maybe with a little limestone or feldspar in it, melts nicely.

I really enjoyed this video. Thanks for taking the time to make it.

I can think of a thousand and one uses for a little blade like that, nicely done. The shape is brilliant.

Yep. My girlfriend was there in April.

Awesome score!

Geoff, thanks for taking the time to experiment and post this. Very instructive stuff!
