OLFA 28 mm Quick-Change Rotary Cutter
This is the size to compare for small appliqué pieces and close changes of direction.

What this tool is for
This is the size to compare for small appliqué pieces and close changes of direction. The 28 mm wheel is smaller than the common 45 mm wheel, so less blade projects along a tight turn. Use it with an appropriate cutting template and mat. If your cutting list is mostly long straight strips from folded fabric, compare a 45 mm model before buying a second small cutter.

Fit and buying advice
The sliding lock releases the blade without the nut-and-washer layout of some straight-handle models. OLFA specifies an RB28 refill. Check the RB28 code on any replacement pack you already own.
Questions about this tool
Will it use the same blade as a 45 mm Splash?
The Splash is a 45 mm model. Use an RB28 on the RTY-1/C.
Is the aqua cutter and utility knife bundle the same listing?
The separate kit adds a small utility knife. This item is the yellow 28 mm cutter identified as 1131976.
Where will I notice the smaller wheel?
Compare it against your tightest template curves and short cuts, where turning space is the main issue.
