My 1st OTFs and now see why they are so popular! Haven’t stopped playing with them! Not sure which models they are as my orig item was oversold…BUT TAC KNIVES made sure I got everything I wanted with the replacement order! Love everything about them, the drop point, single edge, blood groove, swedge, jimping, brushed satin finish, recessed hardware, monagrammed pocket clip, grip texture, lanyard point and D2 to boot. A LOT of features for the USD! Love how they chamfered the touch point edges but left the danger end unchamfered! I’m SOLD!

This was my second order of this model. Well, different variation of this model. Had to order another because the wifey took ownership of the last lol. Perfect size for EDC. My only complaint was the grind was a little off and it wasn’t as sharp as the previous knives. No biggie but I’ll have to resharpen it. Otherwise im happy with the purchase.

I recently purchased this Tacknives MD5TS OTF blade knife and I am highly impressed. It has the Tanto/serrated two tone (black&silver) style blade and the action and quality is remarkable especially for the price. It has a textured handle for added support while in the hand but also slides in and out the pocket with ease. In my opinion this is the perfect size for every day carry. The overall length opened is 7”,closed is 4 1/8” overall but just the handle is 3 3/4”,width is about 3/4” and it’s about 7/16” thick so this fits in a front pocket and leaves plenty of room for other items. I would definitely recommend this knife due to quality,fit and finish. I would also like to complement the Tacknives company on a job well done from the website, to the ordering process, the constant communication, quality products, pricing (coupons & sales) free shipping, customer service etc. It has been a pleasant experience and I will definitely be a return customer. Thanks
