Morakniv Insulation Knife 7350 Stainless Steel Serrated Blade

The Morakniv Insulation Knife 7350 is a long-blade serrated knife built specifically for cutting fabric-covered mineral wool, with a 13.8-inch blade of Swedish cold-rolled special stainless steel and a total length of 19.7 inches. The oversized handle is shaped to stay secure in a gloved hand, making it practical on job sites and in cold-weather conditions where dexterity is reduced.

Built for Insulation Work

A 13.8-inch serrated blade gives the Morakniv 7350 the reach to score and slice through thick batts of fabric-covered mineral wool in a single controlled stroke, rather than the repeated short cuts a standard utility knife requires. That length reduces the number of passes needed per cut, which matters when you are working overhead or in a confined wall cavity where repositioning is slow and tiring.

Stainless Steel That Holds Up to Mineral Wool

The blade is cold-rolled from Swedish special stainless steel, a material choice that resists the fine glass and stone fibers in mineral wool that accelerate corrosion on ordinary carbon steel blades. Cold-rolling refines the grain structure of the steel, which helps the serrated edge retain its sharpness through repeated cuts in abrasive insulation material rather than dulling quickly and requiring frequent resharpening or replacement.

Handle Sized for Gloved Use

The handle is deliberately proportioned to fill a gloved hand rather than a bare one. On a cold job site or in an attic in winter gear, a handle that is too slim tends to rotate or slip mid-cut. The 7350's ample grip keeps the blade tracking straight through the material without the user having to over-squeeze, reducing hand fatigue over a full day of cutting.

Features

• Long serrated blade: 13.8-inch (35 cm) blade designed for cutting fabric-covered mineral wool in full strokes
• Swedish cold-rolled stainless steel: special stainless steel resists corrosion from abrasive insulation fibers
• Glove-friendly handle: ample grip sized to remain secure when wearing work gloves
• Thin blade profile: 0.06-inch (0.14 cm) blade thickness for clean, low-resistance cuts through insulation batts

Specifications

Who This Is For and Isn't

The Morakniv Insulation Knife 7350 suits tradespeople, contractors, and serious DIYers who regularly cut fabric-covered mineral wool insulation batts and need a dedicated long-blade tool that performs reliably in gloved hands and cold conditions.

The 7350 is designed specifically for cutting insulation material and is not a general-purpose camp, kitchen, or outdoor knife. No sheath is listed as included.

Common Questions

What type of insulation is the Morakniv 7350 designed to cut?

The Morakniv Insulation Knife 7350 is designed specifically for cutting fabric-covered mineral wool. The 13.8-inch serrated blade is sized and shaped for this material; fabric-covered mineral wool is the only listed intended application.

Why does the 7350 use stainless steel rather than carbon steel?

The Morakniv 7350 uses Swedish cold-rolled special stainless steel because mineral wool fibers are abrasive and can accelerate corrosion on carbon steel blades. Stainless steel holds up better to repeated contact with insulation material over time.

Does the knife come with a sheath or blade cover?

No sheath or blade cover is listed as included with the Morakniv Insulation Knife 7350. Confirm what is in the box at the time of purchase before assuming any accessories are supplied.

Can the 7350 be used while wearing thick work gloves?

Yes. The Morakniv Insulation Knife 7350 has an ample handle sized specifically to fit a gloved hand, so grip and blade control are maintained even when wearing heavy work gloves on a cold job site.
