I got a new tech bowie and thought i would give it a go with some basic fire work. I only baton kindling so i was a bit surprised at how it took a while to get through a 1.25 inch piece. Yhen i realized how hard it was and had twisted grain. It got through it...but i was genuinly worried about the blade breaking due to the hollow grind. All good. Did brilliant making some curls but the most surprising thing was the amount of sparks it tnrew from a ferro rod..even with the tini coating. A heavy knife....great feel. Just wish it wasn' t so much of a hollow grind. But love it.
