Gents, Ladies,

Quick question. In the for sale section, I see a lot of people say early lockup, or 40% lockup or any one of those terms. Can someone please explain what it means?

Thank you.
 
It's the point of contact of the lock bar onto the back of the blade (tang)
 
In further detail... (right hand lock assumed) the further the lock is to the right, the higher the percentage.
 
People make too much of lockup in my opinion. Different manufacturers have different specifications for what they consider to be safe lockup. Some manufactures like a later lockup while others prefer early....same goes for collectors. I have knives from both of these manufacturers and enjoy them both equally. Most people believe that earlier lockup is better because it allows for wear. I guess that could be true but all of my locks haven't moved in years.
 
People just like early lockup. I dont know why, maybe because early lockup just shows how new the knife is. Actually the later the lockup is the more solid it is. However you would never use the knife in such conditions that you should worry about that. Especially on this knife. Mine has moved a bit in the past two years...but i have flipped it thousands of times.
 
I know of some knife makers with decades of years experience building knives who purposely built them with very early lockup. The harder you grip a framelock the deeper the lockup becomes. Early vs late is an age old debate.
