The OLFA RB45 45mm Tungsten Steel Rotary Blade is the go-to replacement blade for quilters, sewists, and crafters who need clean cuts through up to eight layers of cotton. Backed by 40+ years of OLFA blade expertise, it's the most popular 45mm rotary blade in the industry — and right now it's priced at $10.00, down from $11.99. Buy online at Cutter's Bench and save.
Tungsten steel construction, expert honing, and proven OLFA sharpness make this the blade quilters replace with by default. When your current blade pulls, snags, or skips threads, it's time to swap in a fresh RB45.
Replace your RB45 when you notice skipped cuts, snagged fabric, frayed edges, or when you need more pressure than usual to slice through fabric. Heavy quilters often change blades every one to two projects; a sharp RB45 should glide through 8 layers of cotton with light pressure.
With tungsten steel construction, RB45 blades outlast standard blades — typically several full quilting projects before dulling. Buy multi-packs at $10.00 to keep fresh edges on hand and lower your per-blade cost.
The RB45 fits most 45mm rotary cutters, including OLFA RTY-2 series cutters. If your cutter takes 45mm blades, this blade fits.
At $10.00 — a discount off the $11.99 compare-at price — plus coupon code BENCH10 for an extra 10% off, and free shipping on orders over $45, this is the affordable way to stock up on the industry's standard 45mm rotary blade.

Replaced my old blade with this RB45 before a big quilting session and I honestly forgot dull blades were ever a problem. It sliced through all eight layers of cotton batting and fabric in one pass, no skipped threads, no fraying. Bought two more right away.
I've been quilting for over twenty years and I won't put anything else in my 45mm cutter. The tungsten steel holds its edge far longer than the generic blades I tried last year, and the cuts are clean every single time. Worth every penny, especially at this sale price.
Cuts beautifully through multiple layers of cotton, no complaints about sharpness or fit in my rotary cutter. It did dull a bit faster than expected after a couple of large projects, but I cut a LOT. Still my go-to replacement.
It works fine and cuts cleanly through four layers easily, but at this price I expected it to last longer than a month of regular use. Decent quality, just wish it came in a multi-pack.
One of mine came with a small nick that caught on fabric every pass. Cutter's Bench replaced it quickly, and the replacement has been flawless, so maybe just bad luck in shipping. No issues with the blade itself once I had a good one.
Cuts everything cleanly. Zero skips.
I'm 74 and my hands aren't what they used to be, so a sharp blade makes all the difference. This one glides through fabric without me having to press hard, which means no aching wrist after a day of cutting strips. The clean edges also make piecing so much easier. I stocked up while they were on sale.
I teach beginner quilting and go through blades quickly cutting kits for students. This RB45 handles stacks of cotton without snagging, and the kids' cuts come out straight even when they press too hard. It fits every 45mm cutter in my supply bin, which simplifies ordering.
Did a whole queen-size quilt top from jelly roll strips and never had to press twice. The blade tracked perfectly along my ruler with no wandering. Genuinely impressed with how little force it needed.
Fits my cutter perfectly and cuts cleanly. Shipping was fast too.
I cheaped out with store-brand blades for a while and regretted it with every skipped thread. Switched back to the RB45 and the difference was immediate — one pass, clean edge, no fuzz. For quilting where accuracy matters, this is the blade. The sale price at Cutter's Bench made it an easy decision to buy several.
It cuts fine and fits my Fiskars cutter even though it's an OLFA blade. Nothing wrong with it, just not noticeably better than other blades I've used. May repurchase on sale.
