Features a scale and impact-resistant plastic handle. Review: Great product from Hultafors - Bough this as I plan to insulate a new garden shed. I have bought Hultafors craft and utility knives in the past and despite their very modest pricing I have found them to be some of the best utility knives I own (honestly - check the range out). Have tried this on some spare mineral wool and it cuts beautifully. What I also like about the blade is that it is marked in one cm intervals up to 30 cm. Blade comes with a neat plastic blade guard which can also be used for hanging the knife up when finished. Review: Used for Celotex - Better than serrated Bread knife - Definitely the way to go. Straight clean cuts, very low amount of dust. Much easier to use than a bread knife (easier to direct). Less dust than even with a high TPI saw, but a saw is a bit easier to direct. ## Features - CONTENTS - Mineral wool knife FGK with serrated edge. - DIMENSIONS AND MATERIAL - The insulation knife has an overall length of 465 mm. The blade is 316 mm long and 50 mm high and made of Japanese carbon steel. Thanks to the serrated edge of the blade, very few shavings are created. The handle of the foam knife consists of extremely durable and impact-resistant PP plastic. - EXTREMELY SHARP - The highly resistant blade is particularly strong thanks to its width of 50 mm, allowing you to work precisely and safely. The pointed blade makes it easier to pierce materials. The scale on the blade (up to 30 cm) is used for quick and easy measurements. - USE - The insulation knife is used for cutting rockwool, glass wool, polystyrene, insulating foam, insulating and foamed materials, mineral wool, fibre material, felt and Styrodur. The hole at the end of the ergonomic handle is used to hang the knife. - Hultafors - Quality tools for professionals and craftsmen. Swedish premium quality for professional craftsmen since 1883.

Straight clean cuts, very low amount of dust. Much easier to use than a bread knife (easier to direct). Less dust than even with a high TPI saw, but a saw is a bit easier to direct. ### ⭐⭐⭐⭐⭐ excellent product *by J***R on 23 September 2019* excellent investment for cutting PIR board- struggled with 120mm boards, 90mm boards easier, yet to try on 60mm boards. had i not bought this would have struggled "shaving the board edges to get a tight fit" still used a saw to cut the board quickly using this knife minimal dust, but i still wore a P3 mask only minor downside is that the knife is flexible so have to be careful to keep perpendicular to get a straight cut ## Frequently Bought Together - Hultafors Insulation Knife Made of Japanese Carbon Steel I 300 mm x 50 mm Blade I I Incl.
