The FatMax Extreme 10-817, is a 25mm heavy duty snap off with a 4 blade capacity and automatic blade reload.  At the base of the knife, we have the blade snapper, and on the other side, the magazine to hold up to 3 spare blades with one more in the slider.
To snap off a blade, push the slider forward to the etched line on the blade, and tighten the thumb screw, locking the blade in place. Insert the blade into your snapper, then, with the etched side of the blade down, hold the snapper securely to your work surface, and raise the back of the knife.
To change blades, extend the slider to the forward position, and grasping the blade on the back side, pull it out, while pushing the slider forward. Once the old blade is out, push the slider all the way to the bottom, and it will automatically pick up the next blade.
