Designed by Logan to work exclusively with Logan Simplex mat cutters this V-Groover is by far the easiest system we’ve seen. All you do is set the stops to the size of the V-Groove you desire. Then bear down on the push section of the unit to insert blade into the mat board and move the cutting head to the adjustable stop. Remove the blade and press down on the pull section of the unit and go the opposite direction moving down to the adjustable stop where you first started. Repeat for all four sides and in just minutes you have a perfect V-Groove. Get clean, crisp cornered V-Grooves without overcuts. Set V-Groove widths from 1/32 to 5/64 of an inch. Made to last with an all metal construction. Comes with cutting head, adjustable stop with inch and metric scales, practice mat boards, 6 blades and fully illustrated instructions.
