Touching up a short hawksbill curve with a ceramic rod
A compact serpette knife carries its edge on the inside of the curve, where a flat bench stone cannot reach properly. On a 6.5 cm blade that curve is tight, so a slim rod works better.
- Stand a tapered ceramic or diamond rod upright, tip down on a table, and hold it steady.
- Lay one bevel against the rod at about 20 to 25 degrees and draw the blade across it, using the thin end in the tightest part of the curve and the thicker section where it opens towards the heel.
- Count your strokes, then give the other side the same number to raise and remove the burr.
- Test by slicing a sheet of paper from the brass bolster to the point: the cut should be clean along the whole curve.
