The plural form of drawknife; multiple woodworking tools with blades set at right angles to handles for shaping wood.
This is simply the regular plural of drawknife, formed by adding the standard English '-s' ending to the singular noun.
Craftspeople often collected multiple drawknives with different blade widths and curves for different jobs, much like modern woodworkers have entire sets of chisels—specialization in tools goes back much further than factory manufacturing.
