This is a Rough Rider Sowbelly single blade lock back, i purchased from Bladematrix , It was less than $8.00 before freight. Closed its 4-1/8 inches long and I slowly gound it down to the size below , taking care not to lose the temper. its still not as small as Tom H's on Begining Carvers Corner. I'm still trying to decide whether to take it down smaller or leave it, it carves really well , I'm just having trouble adjusting to it though. PLEASE LEAVE ME A COMMENT AND TELL ME WHAT YOU THINK (GOOD OR BAD)
