@melissabackwoodss: Had some questions regarding the Boker Extension Knife and its lock strength. It’s a heavy-duty cross bolt lock with 2 connection points through the tang. When the knife is locked out in both the long and short position, the 2 thick internal handles pins slide into the the tang, essentially making it a fixed blade. It’s .20” thick D2 blade rests between to thick liners. The thing is an absolute tank and even though it has a peculiar looking mechanism that folds out, it could be classified as fixed.
