If you have ever chopped out waste in softer woods (Pine, Cedar, Aspen, Poplar, etc) then you have felt the frustration of the wood fibers collapsing and tearing out in big chunks with typical bench chisels ground at 25-30 degrees. These IBC chisels fix the problem with a much more acute bevel angle at 17 degrees that cleanly slice through the soft wood fibers instead, specifically when chopping out waste.
