		The following instructions detail how to remove a blade and insert a new one on a craft knife with a collet.

		Step 1 – Open collet To release the blade, the collet which secures it will need to be opened. Twist the collar to the left (with the blade away from you) in order to open the collet and loosen the blade.

		Step 2 – Remove blade Carefully remove the dull blade from the handle and dispose of it.

		Step 3 – Insert new blade Insert a new blade into the slot at the end of the handle.
