Overview

DMT is a diamond sharpening tool maker, and the FWFC is sized and weighted like a compact diamond hone rather than a full size chisel. At roughly 2.5 ounces and under 10 inches in its listed footprint, it fits the profile of a handheld sharpening tool for chisels and plane irons.

The category label here says Chisels, but DMT does not manufacture chisels; its entire catalog is diamond coated sharpening surfaces, folding hones and bench stones. Read alongside the brand, the FWFC name and the light 0.07 kilogram weight, this looks like a diamond hone meant to put an edge on a chisel or plane iron rather than a chisel itself. Buyers should confirm the listing photos match a sharpening stone before ordering, since the category text does not.

  • Roughly 2.5 ounce weight
  • Compact under 10 inch footprint
  • From a brand specializing in diamond sharpening
  • Sold as a single piece

Who it's for

Woodworkers who already own chisels and plane irons and need a compact diamond hone to maintain the edge. Not a fit for someone looking to buy an actual chisel, despite how the category is labeled.

Pros and cons

Pros
  • Diamond surface sharpens faster than oil stones
  • Compact size for benchtop or on site touch ups
Cons
  • Listing category mislabels it as a chisel
  • Grit information is not specified in the data provided

Performance notes

Diamond coated hones cut faster than traditional oil or water stones and hold flat over time, which is why DMT's sharpening tools are common in woodworking shops for touching up an edge between full sharpening sessions.
