Made from high quality CRV 6150 steel, much better quality than its ugly cousins "hardened", "tempered", or "carbon" steel ... you know, the ones that disposable tools are made of.
The bit is 4cm in length and has an outer diameter of 4.4mm to make sure it fits in the recess in SNES cases.
What a deal! I'm so excited about it that I better go lie down.
