Very sharp blade. Review: my fave - This is a replacement for my favorite rotary cutter. I like the safety of the automatically covered blade. There is a setting of the lever to lock it "closed", which had gotten erratic on my old one (now probably 10 years old) that caused some difficulty with not cutting at certain parts of the "WOF" cut. The new one is "smooth as silk" cutting! ## Features - Ergonomic Rubber Grip: Features a comfortable rubber grip design that provides superior control and reduces hand fatigue during extended cutting sessions - Light Weight Construction: Designed with lightweight materials for easy maneuverability and comfortable handling during all your cutting projects - Pressure-Sensitive Blade Guard: Equipped with a spring-loaded guard that automatically covers the blade when pressure is released for enhanced safety - 45mm Rotary Blade: Features a sharp 45mm rotary blade that cuts smoothly through multiple layers of fabric and various materials - Versatile Cutting Tool: Suitable for quilting, sewing, crafting, and other precision cutting tasks requiring clean and accurate cuts ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002QFA8I6 | | Best Sellers Rank | #73,063 in Arts, Crafts & Sewing ( See Top 100 in Arts, Crafts & Sewing ) #86 in Quilting Rotary Cutters | | Blade Length | 45 millimeters | | Blade Material | Alloy Steel | | Blade Type | Rotary | | Brand | KAI | | Brand Name | KAI | | Color | Blue | | Customer Reviews | 4.7 out of 5 stars 424 Reviews | | Global Trade Identification Number | 04901331502668 | | Hand Orientation | Ambidextrous | | Handle Material | Plastic | | Included Components | Rotary Cutter | | Item Length | 1.77 inches | | Item Shape | circular | | Item Type Name | Rotary Cutter | | Manufacturer | KAI | | Model Name | RS45 | | Model Number | RS-45 | | Number of Items | 1 | | Part Number | RS-45 | | Recommended Uses For Product | Sewing, Crafting | | Reusability | Reusable | | Size | 1.8" | | Special Feature | Ergonomic Rubber Grip, Light Weight, Pressure-sensitive Blade Guard, Spring Loaded Guard | | Special Features | Ergonomic Rubber Grip, Light Weight, Pressure-sensitive Blade Guard, Spring Loaded Guard | | Style | Modern, Minimalist | | Unit Count | 1 Count | ## Product Details - **Blade Length:** 45 Millimeters - **Blade Material:** Alloy Steel - **Brand:** KAI - **Color:** Blue - **Handle Material:** Plastic - **Included Components:** Rotary Cutter - **Model Name:** RS45 - **Recommended Uses For Product:** Sewing, Crafting - **Special Feature:** Ergonomic Rubber Grip, Light Weight, Pressure-sensitive Blade Guard, Spring Loaded Guard - **Style:** Modern, Minimalist ## Images ![KAI RS-45 Rotary Cutter 45mm with Spring Loaded Guard, Ergonomic Rubber Grip, Light Weight - Image 1](https://m.media-amazon.com/images/I/71khULar64L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Sharp blade and self-closing. *by S***H on August 23, 2026* I like the design, Self closes when not in use. Very sharp blade. ### ⭐⭐⭐⭐⭐ my fave *by C***K on September 24, 2026* This is a replacement for my favorite rotary cutter. I like the safety of the automatically covered blade. There is a setting of the lever to lock it "closed", which had gotten erratic on my old one (now probably 10 years old) that caused some difficulty with not cutting at certain parts of the "WOF" cut. The new one is "smooth as silk" cutting! ### ⭐⭐⭐⭐⭐ Should’ve bought these years ago *by T***D on February 27, 2026* I wish I’d purchased these a long time ago. I was getting pain in my thumb from repeatedly opening and closing the blade cover on my other rotary cutters. When you’re making a big quilt and cutting for days, that’s a lot of opening and closing the blade cover. I decided to try the Kai rotary cutter as I have their scissors and they’re wonderfully comfortable and sharp. The handle is very nice, it has a wonderful rubbery grip on each side and it’s thick enough to alleviate arthritic pain in my hands. I love the way the blade cover automatically covers up the blade as soon as you stop cutting. This is just so phenomenal that I can’t believe I hadn’t purchased one of these years ago. ## Frequently Bought Together - Kai RS45 Rotary Cutter - TOOLS4FRP Kai 45mm Rotary Blade - Kai Rotary Cutter, Blue --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.my/products/18204121-kai-rs-45-rotary-cutter-45mm-with-spring-loaded-guard](https://www.desertcart.com.my/products/18204121-kai-rs-45-rotary-cutter-45mm-with-spring-loaded-guard) --- *Product available on Desertcart Malaysia* *Store origin: MY* *Last updated: 2026-10-21*
