Review: great tool - easy to use, good build quality, strong and does the job well, very good value for money compared to the more expensive versions Review: Great tool - Superb tool and ideal for the job of removing UPVC window beads. Recommended by a friend and I found it amazingly helpful. My UOVC windows are 15 years old and the beads were quite stuck. I needed to use two of these tools so borrowed my friends tool as well. Far better than trying to use screwdrivers which cause damage to the beads. They have a relatively sharp edge to get behind the beads so be careful. I cut myself twice by being a bit casual when using them. Operator error. To be treated with the same caution that you would for a knife. ## Features - Multi Use - The Faithfull Window Knife is an essential tool for users in the glazing, window, flooring, and lead working industries. - 100mm Stainless Steel Blade - The durable, corrosion resistant 100mm stainless steel blade is built to handle a variety of tasks with ease and precision. - Quarter Moon -The unique crescent shaped blade is even ideal for more delicate tasks such as removing UPVC window beads without damaging the frame and is perfect for trimming and fitting glass, particularly when dealing with curved or irregular shapes. - Soft Grip Handle with Metal End Cap - With a non-slip, soft grip handle, this knife offers comfort and ease of use, even during extended periods of work.

Recommended by a friend and I found it amazingly helpful. My UOVC windows are 15 years old and the beads were quite stuck. I needed to use two of these tools so borrowed my friends tool as well. Far better than trying to use screwdrivers which cause damage to the beads. They have a relatively sharp edge to get behind the beads so be careful. I cut myself twice by being a bit casual when using them. Operator error. To be treated with the same caution that you would for a knife. ### ⭐⭐⭐⭐⭐ Does the job perfectly *by D***9 on 3 September 2024* Good quality and sturdy, seems to be made of good quality materials and is very sharp. Arrived poorly packed though so caution is needed when opening. Would benefit from some kind of protective sleeve with it being so sharp. ## Frequently Bought Together - Faithfull SGWINDME Professional Window Knife Quarter Moon, Multi-Colour, 1 - Quarter Moon Knife Groove Vinyl Floor Sciving leather cut trimming knife and weld seam guide Vinyl Weld Kit --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/142807578-faithfull-soft-grip-window-knife-quarter-moon-100mm-stainless-steel](https://www.desertcart.jp/products/142807578-faithfull-soft-grip-window-knife-quarter-moon-100mm-stainless-steel) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-19*
