180 grit sharpening puck - GIVEAWAY
A coarse aluminium oxide sharpening puck. I had these made but they're not as soft as I'd like, so I'm giving them away. Available only to the UK - as I am just charging £5 for postage.
They can be left soaking permanently. To keep them flat just rotate them every so often in use.
Good for first stage flattening and thinning, major repairs etc.
They do go grey pretty quickly in use.
