Adjustable Cutting Arm for Rotary Cutter

Add on rotary cutter arm with an adjustable cutting width.

You will reach for this cutter so often! Many uses.

Use for trimming down seam allowances on patterns, adding seam allowances, lengthening/ shortening curved hem allowances. A must for trimming anything that is on a curved line. Cutting down seam allowances on patterns makes sewing the garment so much easier with much better results. Use when making shirt collar bands, cuffs, setting in sleeves, and finishing waistbands. It is so much easier to control fabric and achieve a desired result if you trim all of these areas down to 3/8" before you start sewing. A standard pattern uses all 5/8" seam allowances and is a recipe for disaster in these areas. A 3/8" seam allowance allows precise control and makes it easier to ease in fabric. You won’t believe how much easier those tricky areas are to sew with a smaller seam allowance. Trim excess off on curved waistbands before finishing inside edge with bias tape. Just set the adjustable width arm and whisk off the excess seam allowance accurately. Now you won’t have to measure and mark around your pattern to add or decrease from the pattern. Enlarge or decrease quilt blocks easily and precisely. A must for those who draw their own patterns and add seam allowances. In many instances this is easier to use when cutting straight lines of small width than with a rotary cutter ruler, no need to hold a ruler in place and move around. Use left or right handed.

How to use:

Push back safety blade cover to expose blade. This blade is very sharp so handle it carefully and watch out for your fingertips (personal experience)! Lightly place the blade on your cutting mat ruler or tape measure, move the arm to the desired width and lock into place with screw. Always slide safety blade cover back into place when you finish cutting. Adjusts from 3/16" to 1-3/4".

If you have a 28, 45 or 60mm Olfa rotary cutter (with a hole in the handle recessed in the safety slide area), you can add this arm to it easily by screwing in one, ½" long self tapping-screw (provided) to hold the plastic post in place. We also sell a 45mm Olfa Rotary Cutter with the arm already attached (pictured at top of page). If you have a rotary cutter from a different manufacturer, you may have to drill a small hole to accommodate the screw and post, and may need to use a longer screw depending on the thickness of the handle (longer screw not provided). The length of the stainless steel arm is made to fit with the 28, 45 and 60mm Olfa rotary cutter hole placement.

Post is made of plastic, collar and screws are made of metal, and arm is made of stainless steel.

Durable with trouble free care.

Rotary cutters are to be used only with approved rotary cutting mats underneath.
