Another recommendation for the ZT 0550 here. It's not as pretty as some of the others, but it is a very robust tool. The S35VN has been a great surprise-- I expected it to be great, but it has proven to be a perfect mix of edge retention, toughness (yes, I have done prying with it), and ease of maintenance. The handle really fills the hand. I thought that might be a bit much until the first time I had to spend an hour straight using it. Zero hand fatigue, total comfort. The action on mine is glassy once I defeat the sticky detent. Having had time to break it in and practice, I can flick it open quickly and consistently now. Lock up is air tight. Lateral support... washers and open position stops... Awesome.
This is about as tough as it gets.
