Customer Reviews

Excellent California Complaint Auto
Evan A. on Dec 31, 2021

I just received my Pro-Tech Half Breed. I live in California, so automatic blade length must be under 2". I've already purchased a Pro-Tech Calmigo from Blade HQ, but I like the size and fit of the Half-Breed handle more. I was apprehensive about the small blade with the larger handle, but it looks great and I am extremely pleased with this knife. This knife has become my EDC.

Best knife ever!
Roger A. on Dec 21, 2021

I'm 75 and have owned and used more knives than I can count as an outdoorsman, youth outdoor recreation leader, retired serviceman, and personal protection instructor. I was given a Pro-Tech Half Breed as a promotional gift over a year ago. I use it almost daily - including to cut-down cardboard boxes (an notorious edge killer for knives). This knife came razor-sharp and keeps an edge for a long time. NOTE: I sharpen it periodically with RUIXIN PRO RX-008 Professional Knife Sharpening System that I use for all my kitchen knives. The mechanical function is also second-to-none.

Cali legal with full size handle!
Joseph M. on Mar 14, 2019

I’m from California and I never have an interest in autos. I then realized the launch 4 from kershaw was a Cali legal auto, but didn’t like that the handle was so small. So I checked what autos were under 2”. I then found the protech half breed with a full size handle and the rest is history!

Excellent knife in every way.
Charles W. on Dec 18, 2018

Extremely well made and beautifully finished. Quick deployment, solid lock-up, sharp blade, and a comfortable handle and functional pocket clip. Fits nicely in a dress shirt pocket or dress pants pocket. Comparable in every way to my Microtechs and much more refined than any of my Benchmade, Gerber and Blackhawk automatics.

I love this knife
James H. on Nov 23, 2017

Feels solid, locks up like a single piece of iron and the action is snappy and strong. It feels like a tool n the hand. Very good looking style. I don't carry it and have not used it. The cool factor for me is on point.

Ty L. on Jun 25, 2016

I got this knife in a trade from my buddy and its absolutely gorgeous! The action is outstanding I highly recommend it.
