Extrema Ratio T-Razor Satin pocket knife

The Extrema Ratio T-Razor is an exceptional pocket knife, based on a straight razor blade. That'll come as no surprise, given its shape. Back in the early 20th century, almost everyone carried a pocket knife. This also brought about the first weapon laws, which restricted the types of knife you could have on you. Suddenly, pocket knives were no longer allowed to have a pointed tip. This led to people spontaneously breaking the tips of pocket knives to make them “legal”. Some people switched to carrying straight razors. This “abuse” of the straight razor inspired Extrema Ratio to design the T-Razor.
