Best Side Opening Automatic
Robert B. on Jan 26, 2023

Before purchasing this knife I had a Boker Kalashnikov and thought that was an amazing auto. While it is very nice for the price point this knife is better in every aspect. The action is super crisp and fires hard. The handle is ergonomic and the blade shape is very utilitarian. If I had to have one complaint about this knife it would be the pocket clip, however I am planning on getting a lynchnw clip replacement here soon. Don’t hesitate to buy this knife if you’re able to.

Snappy action
Hung T. on Mar 15, 2018

I call this one "Red Snapper". Typical Protech action w/solid lock-up and beautiful fish scale aesthetics. A button lock and deep carry pocket clip would put this one over the top. This was my first Protech but won't be my last.
