    Good Knife - With a Caveat

    Posted by Greg H. on 13th Jan 2019

    Purchased this knife here. This a good quality knife at a good price. The materials are good, it's very thin in the pocket and just plain looks good.

    However be aware that this knife cannot be flipped open by the thumb stud without great, great difficulty out of the box. The size and location of the thumb stud combined with the very strong detent make one handed deployment nearly impossible. I had read other reviews that said the same thing and wondered how bad can it be? They're right, it's that bad no matter where you grip it.

    There is a fix. I disassembled the knife and lubed it, but more importantly sanded down the detent ball by at least 50%. Upon reassembly it flips open as it should with no change to the size or location of the stud, and the detent is still strong enough to serve its purpose and keep the blade closed.

    My review would have been 5 stars out of the box had it not required this effort to repair it to the condition it shoud have had from the manufacturer. This downgrades it two stars.

    I highly recommend this knife if you are willing to take the steps that I did. If you aren't willing or able to do this then understand that you will get a knife that will either require an aftermarket thumb stud or it will be a two-handed opener. If you're okay with that, then it's a good knife at a good price.

high quality. high performance
