I bought the black coated mini with the knife blade, blade is sharp enough. The scissors will be what breaks first. They are spring tensioned and the spring gets compressed when closing them back into the handle. The pivot screw on that end came loose in my car from driving. Tightened it up. The small screwdrivers are difficult to open, but they have tabs. The bottom portion of the bottle opener is a pocket lining hole poker but will open bottles and cut packing tape. Serviceable and a decent companion for mp 400 600 series, suspension series etc.
