Elu Bevel Edged Chisels - 1 For Restoration

One is 3/4" 18mm made by Clay (Sheffield) in general ok but top ege of handle looks like it may have been shaved off a little.

The 1/4"/6mm is likely Clay as well but name rubbedd off reverse side.

The other is marked 1/2" / 12mm and also Clay, this has been ground on the edge to a curve as shown.

All that being said these are pretty rare chisels to find and source.
