I'm not pimping these... you asked about it.
I'm selling MTech's kerambit. It is probably nothing compaired to Emerson's or Tarani's kerambits... those guys are both something else. But this knife is only 20 bucks.
It's a heavy, solid, tank-like folder. The lock up is very solid. One of the strongest for a liner lock. In fact, some are even hard to unlock when new. G-10 scales. Pretty sharp blade. The pocket clip is oriented point down so it carries like a normal folder. The pictures make it look small, but it's actually big and beefy. Fills my hand.
Mine has the black coated blade. I've also ground down the G-10 along the edges to contour the grip so it feels better in the hand. I also polished the friction bearing surfaces inside, so it opens real smooth with the thumb, or easily with a snap of the wrist. Pretty dang good for only 20 bucks in my opinion... not as expesive as the other Kerambits. Probably not as good either, but it's still a good knife.
I've been practicing with it, and funny... I have the same mark on my wrist as yours. Exactly. Bled like broken milk jug. Super glued it shut and it's fine now. I don't think I am going to be trying that move again!
As for the flipping routine... it looks very flashy and cool. But I think my technique will be snapping it open like I do with a normal folder and just using it in a reverse grip.
As a utility knife, it's great for gardeners. With the pinky through the ring you can work your plants, and then flip it up to trim a twig, harvesting a veggie or making a splice... I've done this and it worked perfectly. Not to undermine any tactical use or anything, it's just a real useful knife for certain applications.
Watching those Emerson video clips. Whoa! That guy is fast!
