I have no first hand experience with these, but I'll throw out my semi-qualified opinion anyway.
Overall these seem a bit overpriced for what they are. All of the knives are made with 5/16" 5160, which is about as inexpensive as knife steel gets. There is probably no more than $50 in materials, even in their largest pieces. You are basically paying for their time in making them, and they state as much on the front page of thier site. 5160 is a totally appropriate material to keep the cost down on the large machette and sword type pieces (and for it's spring steel properties), but a bit out of place for the smaller stuff. I would prefer a modern stainless knife steel for a small to medium piece. A modern high perfomance stainless would likely out- perform the 5160 and justify their price tags. For the amount of money they want, I would go with a semi-custom maker using a higher performance steel.
Same goes for the thicker 5/16" thickness, which just makes a small knife heavier than it needs to be, and a heavy piece even heavier. That weight is great when trying to chop through things, but sucks when lugging the knife around.
Their craftsmanship seems fine for a utility knife, but the most important factor for a 5160 knife will be the heat treatment, which you can only evaluate by using the knife. Again, overall their prices seem a bit high for the materials they are using and a knife shop that looks like it popped up last year.
