It cuts through fiberglass easily without any part of the handle being close enough to snag or bunch up the insulation. It makes cuts quick and simple in one step. I read some reviews saying that it is pricey for what it is but I disagree. It is well made. The thumb screw is easy to operate with just a thumb for easy one handed release and securing. The blade is holding up well after over 30 cuts so far and I'm still on the original tip. Review: Wonderful tool! - This was recommended by a YouTuber so I tried it out and love it! I'm so used to really solid razor knives I was concerned in ordering it but having used it a few times cutting drywall I love it. The handle is easily gripped and the blade is more stiff they I expected - though you can extend it out to make it a little flexible to cut things off flush to a surface. It probably won't cut carpet like my very solid, old-fashioned razor knives, but it'll do almost anything else except those really heavy duty jobs. ## Features - RAZOR SHARP 25mm BLADE - Preloaded with HB Extra Heavy-Duty Snap-Off Blade from Japanese tool steel for unmatched sharpness and edge retention. The 25mm blade has 7 razor-sharp snap-off segments, great for industrial or construction applications. - STURDY PLASTIC HANDLE - Made from high-impact ABS plastic, our symmetrical handle design features an anti-slip rubber inset for additional grip. The stainless-steel channel keeps the blade firmly in place for safe operation. - CUSTOM RATCHET LOCK CONTROL - Designed with safety in mind, our box cutter's ratchet-based locking system provides custom cutting depths. The blade slider has a wheel locking mechanism for unlimited positions when securing the blade in place. - MULTIPURPOSE EXTRA HEAVY-DUTY DESIGN - The OLFA 25mm H-1 Retractable Utility Knife is perfect for cutting through the toughest materials. It delivers accurate cuts through nylon, rope, laminates, leather, rubber, gasket materials, and more. - THE OLFA STANDARD - As the original inventor of the Snap-Off Knife, OLFA has maintained a standard of cutting excellence for our quality and durability. Pairing your OLFA 25mm Utility Knife with OLFA 25mm Blades will provide optimal results. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001DKOQGU | | Best Sellers Rank | #20,212 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #113 in Utility Knives | | Blade Material | High Carbon Steel | | Brand | OLFA | | Brand Name | OLFA | | Color | Yellow | | Customer Reviews | 4.8 out of 5 stars 1,189 Reviews | | Global Trade Identification Number | 00091511600117 | | Handle Material | Abs, Plastic, Plastic Handle, Rubber , Stainless-steel, Steel | | Handle Type | Manual-Retractable | | Included Components | Assembly Guide | | Item Highlight | 25mm Japanese tool steel snap-off, anti-slip rubber inset, ratchet-lock - Heavy cutting - Contractors and Construction | | Item Length | 5.25 inches | | Item Weight | 4.8 ounces | | Manufacturer | OLFA | | Manufacturer Part Number | 5006 | | Manufacturer Warranty Description | guaranteed forever | | Material | Plastic, Rubber, Stainless Steel | | Material Type | Plastic, Rubber, Stainless Steel | | Model Number | 5006 | | Number of Packs | 1 | | Product Style | Industrial | | UPC | 091511600117 091511200188 | | Unit Count | 1 Count | ## Product Details - **Blade Material:** High Carbon Steel - **Brand:** OLFA - **Color:** Yellow - **Handle Material:** Abs,Plastic,Plastic Handle,Rubber,Stainless-steel,Steel - **Item Length:** 5.25 inches - **Item Weight:** 4.8 ounces - **Material:** Plastic, Rubber, Stainless Steel - **Number of Packs:** 1 - **Style:** Industrial - **Unit Count:** 1 Count ## Images ![OLFA 25mm Extra Heavy-Duty Utility Knife (H-1) - Anti-Slip Rubber Inset - Image 1](https://m.media-amazon.com/images/I/41BGSXKuhWL.jpg) ## Questions & Answers **Q: I have 18mm knife and blades are thin/flexible.
