My Favorite Auto So Far!
FRANK R. on May 10, 2021

I now own 19 pocket knives and 8 of them are automatics. The Pro-Tec TR-5 Automatic is my favorite so far. I would say my Benchmade Mediator Auto is my runner-up followed by my Microtech UTX-85 T/E OTF Automatic. This knife has quality written all over it! For me, it is the perfect size EDC. I also love deep carry clips. I like the blade action on this knife along with the S35-VN steel blade. I like the blade shape and overall appearance of this knife. This knife being made in the U.S.A. is also a plus. I would definitely buy this knife again!

EDC Auto Perfection
Adam T. on Aug 5, 2020

This is my first TR5 and man I must say that I love it. It is absolutely a perfect edc auto piece. The size, the blade, the materials and fit are all there. The one thing that I love is the deep carry pocket clip. It doesn't feel like an afterthought like most others. It is integrated into the handle. The clip and clip screws all sit flush with the surface of the handle and do not snag at all. I only have one gripe. The steel back spacer that is used doesnt have the same level of finish as the rest of the knife for some reason. Should you purchase this knife after 08/2020 please make sure they have fixed this if that is keeping you from buying it. I wouldn't let it deter you, I didnt. I'm not saying it is bad. However, given Protech's typical high level of fit and finish, make it all that more obvious. This is an awesome knife at a great price for a premium auto. I am sure they will continue to improve upon it. Great Job Protech. Looking forward to the next iteration.

Great Investment
Pedro G. on Sep 4, 2019

I love the all around feel of the knife and how it fits in my hand. Super sharp bladed edge originally from factory. The deep carry pocket clip is a huge plus that already comes with the knife and most of all, the best part is just that auto open and lock that is assuring and gratifying. Words don't do it justice, it's just something you have to experience for yourself.

Gold Standard of Autos
Bruno M. on Sep 5, 2020

This is my 3rd ProTech I've purchased and by far will be the one that sees the most pocket time. Great Protech snap action. Deep carry pocket clip is a plus as well. I typically carry thinner knives as my EDC to work and was a bit worried it would take up too much space in my work pants pocket but it hasn't been an issue. I haven't really had a need to use the safety lock on the action but I still think its a great feature.

Worth Every Penny
Allan M. on Mar 2, 2020

This is my first Pro-Tech but it won’t be my last. Sleek minimalist design beautiful to look at and feels better in the hand. Small footprint for a knife with a 3.25” blade. Much more compact and lightweight than my comparably blade sized Boker, ZT’s, and SOG. Slide it into your pocket with the deep carry pocket clip and it disappears in your pocket and so lightweight you hardly notice it. Build quality is spot on with tight tolerances. Perfectly centered and razor sharp right out of the box, I mean shaving sharp. Blade flies out at the touch of a button with a satisfying thwack. The S35 vn blade is high quality steel. Lock up is rock solid with absolutely no blade play. A lot of people don’t like the blade lock but I like the extra assurance when I drop it into my pocket. Wouldn’t hesitate to recommend this knife.

Snappy Automatic!
Ken C. on Oct 6, 2019

When I finally pulled the trigger on my first automatic, I initially figured it would turn into a safe queen with most of the rest of my collection being manual flippers. This knife has spent the most time in pocket since I acquired it. The S-35VN blade steel holds an edge very nicely and is reasonably easy to sharpen using my Wicked Edge sharpener. The aluminum handle scales are sneaky grippy and the action is what Protech is built up to be. The only con is the safety. I carry this knife in my front right pocket and the button has never mis-fired the knife, while the safety has been inadvertently activated in pocket. In my opinion, this knife doesn’t need a safety at all. I look forward to adding other Protechs to my collection soon!

Nice Knife
John M. on Jun 6, 2019

This is a great knife. The size, finish and feel are perfect. The blade is perfect and the action is solid. It has a very snappy deployment. I have never had a misfire. When you carry it and deploy it, you can feel quality of USA craftsmanship. I have one issue with this knife however. And this is just my issue, nothing takes away from the quality of the item. But I do not like the safety at all. I wish it did not have the safety. Or at the very least, I wish the steel used for the safety latch matched the steel used for the deployment button and blade.It just stands out and look out of place. Other than that, I think its a great knife. I have owned low end to mid range automatics made in USA, this one is worth the extra money.

Quality Knife, but, EDC? Not looking good.
Tim M. on May 11, 2021

Very well made EDC Auto, EXCELLENT steel, razor SHARP. Great feel on this knife and would have got into my pocket immediately. < Except for the BAD below. On the PRICEY side $$$ and really begs the question is it worth $200 more than a Kalashnikov. Pet peeve of mine is poor POCKET CLIP design (bad / not stable platform, allowing the clip to turn and ultimately loosen the retaining screw(s), this one has a GREAT design and is possibly a STANDARD for other manufacturers. Lastly,... the BAD,... this knife has one flaw, the safety. It only works as a safety to keep from accidentally opening the knife and does not allow the blade to be locked in the open position. Simple tooling would have allowed the safety to work in both open and closed modes,... Unfortunately, it needs it as It doesn't take much manipulation to find a position where my thumb, in a tight grip can actuate the lock (button) and release the blade, (say goodbye to multiple fingers)... Kinda bummed because I really wanted to carry this one, but unfortunately, this one may become a safe trinket.
