[QUOTE=nativetexan;7861401]yes, but do you have the 28 rotary cutter itself? those blades will not fit the 45. I use the 45 almost all the time. i tend to pick up my 28 when ripping out seams but not for much else. the blades were on the rotary cutters, so 2 Sets for $10 . Even if they get dull faster, still a good deal.
