Query: some assembly required

These are impressive looking hammers, but they arrive in pieces that require assembly. The assembly is easy, but I was dismayed to find that the languets (the steel sides below the head) are actually separate pieces. The screws supplied to attach them do not seat completely flush, and they are so mild that, even with pre-drilling the holes, some of the heads snapped off before the screw was fully seated. I am surprised,because Cold Steel usually makes some fine weapons. On a side note, the 30" handle is a bit awkward for single-hand use, but a bit short for two-handed. Also, if they are to be used in any combat scenario, the rear spike is rather sharp, and needs to be dressed down for safety.
