Benson's News

The Janser Green Knife is the preferred roofers’ knife. The Green Knife is a large framed knife that pivots open to change the blade. The heavy duty construction makes it perfect for cutting roofing materials, sheet goods, carpeting and other tough materials. The length and unique shape provide the user with more leverage and less scraping of the knuckles.

  • No tools required for blade change · 20 German blades in convenient dispenser & Holster included

  • Shape designed for non-slip grip

The vast majority of roofers’, carpet installers, and many other professionals that have used the knife, prefer it over any other utility knife they’ve used. While it is more expensive than an average knife, the cost is heavily outweighed by the benefits. Durability, efficiency, ergonomics, convenience all add up to making life a little easier for the user.

At Benson's Building Supply we take pride in the fact that we are one of the few retailers in the area that are fortunate enough to be able to carry the Janser line of knives. Since these knives are imported from Germany and carry a large reputation with the construction industry, Janser is careful with who they allow to represent their name. Benson's long standing reputation and dedication to great service and quality products allowed us to become one of those lucky retailers.

Product Includes: 1 Green Knife with 20 German Deep Hook Blades and a carrying Holster.

I have used the Janser Green knife for three years now and wouldn't switch to any other knife if you paid me! Well worth every penny. Stays sharp cut after cut and never breaks.
