セラミック替刃（鋭角刃先シームリッパー）

I do leather work and the seam ripper pointed blade appeared to be a desired usable cutting tool we used it a week ago and it did well .I plan to give a presentation Via Zoom to the members of the Lone Star Leather Guild ,which includes members in at least 7 other countries and across the USA. I plan to have attending members use or try as many of those samples you sent me. I want to give the viewers & attendees as much exposure as possible. I also have 20 catalogs to give attendees Thank You T.J. Sincerely, Bob Bishop
