Dave, there is a hobby machinist on You Tube called “This Old Tony” that has recently made this Tap Wrench that looks much like your rendering, It is remarkably like what you have pictured here.
I’m glad you see the similarity because I used his wrench and indeed the dimensions he provided to model mine. The only difference is I used the diamond knurling while he use linear knurling.
Simple beautiful work.
Very nice renders. What renderer are you using?
The renderer is Kerkythea.
