What are the physical dimensions and weight of the LMF II Knife?

The Gerber Gear LMF II Infantry Survival Tactical Knife has an overall length of 10.59 inches and weighs 24 oz when included in its sheath.

The 4.84 inch blade length refers specifically to the cutting surface and does not include the handle or guard. For users concerned with carry weight, the knife itself weighs 11.67 oz, while the ballistic nylon sheath with fire retardant coating adds significant mass to reach the 24 oz total. We selected this survival knife for our review because it features a 420HC stainless steel blade that doubles as a pommel and includes lashing holes for spear use. Because tactical knives are often carried in high-stress environments, knowing the exact weight with the sheath is critical to prevent fatigue during long-duration transport. The blade geometry provides a partially serrated edge, which affects the effective cutting length compared to a standard smooth blade.

What to Check Before Buying the LMF II Knife

Before purchasing, verify these specific physical details to ensure the tool meets your requirements:

• Confirm if the 4.84 inch blade length provides sufficient reach for your specific tasks, as this measurement excludes the handle.
• Verify the handle grip diameter to ensure it remains ergonomic when wearing standard combat gloves.
• Check the blade stock thickness with the manufacturer to determine its durability against heavy impact versus its ease of sharpening.
• Confirm the exact weight of the 420HC stainless steel blade to ensure it meets your balance requirements for one-handed use.

Sizing and Weight Considerations for Survival Knives

The LMF II Knife serves as a heavy-duty fixed blade for outdoor survival and tactical utility. While this model provides a robust 24 oz package with a MOLLE-compatible sheath, some buyers may find the weight excessive for lightweight hiking. If you prioritize a minimalist profile or a lighter carry weight over the added features like the built-in sharpener and lashing holes, you may want to look at alternatives with lighter blade steels or more compact sheathing systems.
