For me the best way to trim a m'room tip is to use a japanese kiradashi knife. SHARP as fk and goes thru leather like shit thru a goose. just tape off the ferrule, trim, polish the side of tip with super fine sandpaper and burnish. done. https://www.knifecountryusa.com/sto...h7213j7xe4LCxAE0jzAmVg21zC_q0hoRoCsg4QAvD_BwE
