What can you say... it's bullet proof!
marcello a. on Jan 10, 2020

I have many knives but this is at the top of the list as far as durability and for all around it's slim enough to carry easily. It's a winner!!

Happy Lefty

ProTech TR-3

Love the Pro Tech quality which is why I bought my second one. Also meets my needs as I am a left-hander.

Tr3 l-1

I'm not really a big auto guy. When I saw a lefty model I thought why not. Really impressed simple classy and well made product. Blade doesn't look like a billboard fires hard locks up every time. Perfectly centered blade, pocket clip slides nicely in and out of pocket like it should, not gonna shred your jeans. The blade is a little thicker than I normally carry not a perfect apple slicer, but it is designed as a tactical knife not a kitchen knife. the swedge and flats are very symmetrical, the only flaw I can see is the edge grind is slightly different from one side to the other near the tip. Most people wouldn't notice. I'm pretty anal and checked the whole blade under magnification. At this price point I don't think you will find craftsmanship any better from any of the U.S. made brands. For me it's a ten out of ten product. Should note mine is the bright stonewashed blade. the link wouldn't let me leave it there. Maybe I need a black one too?

Finally a lefty auto

I love this knife! Full time carry for around 8 months now. Solid lockup, hard opening, super durable black finish.
