Unless you're intentionally trying to make it cut your finger, the little bit of exposed edge in the compression lock cutout is not actually a risk with the Tropen. The flipper tab hits your finger when closing, so you're forced to move your finger out of the way.
It could be considered a little too wild for some peoples taste, but I think it's a really cool design. I liked it more after actually handling one, the rounded scales feel really great in hand. I'd be interested to know how well it's selling though.
In my opinion, S30V is plenty good for the design but if it's selling well enough for Spyderco then maybe a sprint could be worth the investment.
