The way I understand it. The 112 was created when the Navy made a rule about the size of folding knives they would allow on ship. After somebody was stabbed with a 110.

This is were the 112 fits in, when the 110 is prohibited. Otherwise you might as well carry a 110. I have always liked the way the front bolster on the 112 flairs out just enough to form a guard of sorts.

Really high quality knife, I'm sure you'll be happy with it.
