     Last year I stumbled upon a pattern that was so interesting and bizarre. By the geometric wizardry of mathematician Roger Penrose it all fits together with no space or overlaps while having fivefold rotational symmetry. I immediately thought I’ve got to figure out how to pull it off in pattern welded steel. Shortly after I found myself down at Steve Schwarzer’s shop and together we spent a collective 20 hours just getting a billet to a forge welded state. 

     Alright enough of an origin story, the blade has a B-grind for food release and to manage a thicker, more rigid spine with a thinner blade for less resistance in the cut. Of course I say thick meaning at the base of the spine by the integral bolster. It tapers beautifully to a very fine point for delicate detail work. The handle is mechanically secured and everything is stabilized and heirloom fit so that if anything ever does shrink or swell no sharp corners will ever show up.
