ISELI FL · Wiki
Wood chisel, mortise chisel, firmer chisel: one tool, many names
Depending on region and trade, the same tool goes by different names. For sharpening, one thing matters: a straight cutting edge with a clean, consistent bevel angle.
Firmer chisel
A sturdier chisel with a thicker blade, designed to be struck with a mallet.
Mortise chisel
Narrow and thick for cutting mortises. It also needs a perfectly straight cutting edge.
Paring chisel
A thin, flat chisel for fine fitting and finishing work, guided by hand.
The ISELI FL sharpens all these flat chisels and plane irons reproducibly, whatever name is on the blade.
Request a quotationFrequently asked questions about chisel sharpening
What is the difference between a bench chisel and a mortise chisel?
A bench chisel has a wide, flat blade for paring and fitting. A mortise chisel is narrow and thick for cutting mortises with a mallet. Both are sharpened the same way.
What sharpening angle is right for a wood chisel?
For most woodworking, a bevel angle of about 25 to 30 degrees has proven itself. More important than the exact value is that it stays the same every time you sharpen.
How often should a chisel be sharpened?
As soon as the edge crushes wood fibres instead of cutting them or shows chipping. In joinery and carpentry workshops this is often weekly.
Why a sharpening machine instead of a whetstone?
The ISELI FL sharpens in seconds, always with the same angle and a straight edge, without honing. This saves working time and extends tool life.
