"bought this knife few months ago and it jammed as per the first reviewer,even tried releasing with a pair of grips but no joy ,i have various irwin hand tools and no probs but this knife is a waste of cash ,"
"Bought this a couple of weeks ago. Looks and feels good. However , after a couple of blade changes and cutting plasterboard, the quick change button no longer releases the blade. Try to undo the tiny screws inside to open it up and it is a pain to get back together. A waste of money. No longer use it"
