Thumb Stud in stock
A thumb stud is a small post fixed to the side of the blade near the handle that you push with your thumb to open the knife one-handed. It is the most common opening feature on modern folders and it appears on hundreds of the knives we stock.
A dual thumb stud has a post on both sides and works equally well left or right handed. A single stud is on one side only, which is lighter and cleaner but handed.
Some studs are adjustable, letting you set how far they protrude. Others double as a blade stop, contacting the handle to limit travel, in which case removing the stud is not an option.
Push out and around rather than straight up. The blade rotates, so following the arc with your thumb rather than pushing against it gets the knife open with far less effort.
Sharp-edged studs can be uncomfortable after repeated openings. A rounded or knurled stud is easier on a bare thumb than a small hard-edged cylinder.
The term is not academic here. 290 of the products currently on our shelves describe this feature in their own manufacturer specifications, across 8 of the nine brands we stock.
