EX1000138: T-Razor Black
Extrema Ratio
Up to the early 1900s, people commonly carried pocket utility knives. Due to rampant misuse, laws were passed to the effect that all such knives were to be clipped at the blade tip, in order to diminish their intimidation factor as weapons. Some people then figured they'd get the greatest effectiveness out of the sharp edge of a traditionally flat-point blade shape and took to carrying straight razors. Thus, the straight razor was for a time regarded as a fearsome weapon of self-defense. Such a misuse of the common straight razor inspired T-RAZOR design.

Pros: Blade Material, Blade Sharpness, Handle Material, Overall Quality
Cons: None
Nice entry quality for extrama's low end line up.
Although construction is relatively simple, the anodizing and machining of this knife is great for the price. The edge is super thin like a razor, and it's really razor sharp. Don't expect any hard use on it.

Pros: Blade Material, Handle Feel, Weight, Handle Material, None
Cons: Overall Quality, Lock Type, Sheath, Pocket Clip, Lock Ease of Use, Blade Sharpness, Ease of Opening
Not to the level I though from Extrema Ratio
First: how you carry it ? the extended blade tang open it very easily and from a small touch, not very interesting in a pocket, in a lanyard … two: the liner lock do not lock deep, if you do not open it strong … and like on a 1911 with his grip safety, a extended tang that protube will ease to engage firmly it. third: again the liner lock, I do not like the new tendency to have the liner lock flush with the grip and the smallest opening to disengage it, but for this knife, I think it will be better, like it is now, you can disengage the liner lock much too easily and because the handle is large, there is real possibility that you will not have your hand on the tang to block it open. Four: a kydex shealth like Fred Perrin do for is Bowie friction folder will be a must have for it. Five …. it is not at all razor sharp ………..
