Sharpening Tips from Tom Blodgett at jendeIndustries.com
The Pantzier reed knife is basically a single bevel knife with a radius tip. The bevel portion of the blade is sharpened as usual by following the bevel angle. The radius is the tricky part, which requires a compound motion of matching the bevel while raising the handle to match the contour of the tip to come into contact with the stone along the entire radius. This is definitely a more advanced technique. The softness of the steel puts the optimum operating sharpness between 600 and 2,000 grit, and will benefit more from being reinforced with a micro bevel, or secondary bevel.
