thanks Nick for giving me the money for some lovely new chisels, they are a joy – two used already, the odd French one for the Pranayama stone and the big lettering one in use now on Hillside Cottage

6mm bullnose, 4mm lettering, 4mm new eccentric French, 12mm lettering

the big one I’ve had to re-sharpen too make the tip more angled and fatter than I would normally as the Purbeck Thorn Back limestone for Hillside Cottage is amazing, virtually all shell, and kept taking chunks out of the chisel. The photo shows it sharpened with the angle into the tip (there’s probably a technical name for it…bevel?) and another chisel without that for comparison.

they’re resting in the diamond pad I use with water to sharpen them. I normally don’t put a bevel on them and keep them long and tapered (drawn out) so you can do the fine angled work for lettering. now I can’t use the big one to do the serifs on this job – in the picture below the serif is half carved using the 8mm chisel.
