Understood. All my recent dovetailing practice has clearly illustrated the fragility of the baseline, especially if trying to remove too much waste at once. My point was that on certain wood, the crisp but shallow line from the wheel gauge doesn't offer much in the way of registration, Whether it be for supplementing with a marking knife or for establishing a chisel wall/knife wall.
Sharp solves all manner of problems.
