my hand fits in the cutouts, but it's a little tight. and it's too big to really stretch farther to put my pinky on the last section. there's definitely only one way for me to hold it in the hammer grip, but it works and i'm enjoying the fact that it's a cool looking spyderco with the longest blade i can legally carry. i used it a bit at work today and love the fine tip, just like the yojimbo.
while i never thought the ergonomics would work for me on this knife, they are definitely passable. and, to be fair, the yojimbo is the same for me in that it's not the most comfortable knife to hold. they are just too cool to care though. also, the texture reminds me of the recon and i like it.
