In the past most Bladesmiths / Blacksmiths made drifts and other tools needed, most still do and a drift is about as basic as it gets...
Obviously I'm assuming you want an eye drift to forge a Tomahawk? If you have the ability to make a Tomahawk an eye drift should be really, really easy to make.
Apologies if I'm making assumptions that don't apply, meaning you want the drift for something else!
