A corner punch is a hardened steel cutter with a curved edge that rounds off square leather corners in one clean mallet strike. Rounded corners resist peeling, snagging, and wear far better than sharp ones, and matching every corner by hand with a knife is slow and rarely symmetrical, so a punch gives home leatherworkers an instantly more professional result on wallets, straps, and cases. Most makers want two or three radii, a small one around 5-10 mm for card slots and wallets and larger ones for bags and belt tips. When comparing punches, check edge sharpness and steel hardness, a comfortable strike head, and whether the radius is clearly marked for repeat use.
