Frequently Asked Questions (FAQs)

1. What is the difference between a snap knife and a utility knife?

The main difference between a snap knife and a utility knife is the cutting depth. Utility knives typically expose only about 3/4-inch of the blade, limiting the cutting depth. On the other hand, snap knives have retractable blades that can extend a couple of inches, allowing for deeper cuts in materials like foam insulation.

2. What not to do with a utility knife?

When using a utility knife, it is important to avoid certain actions: - Applying excessive force as the razor-sharp blade can cut most materials with light pressure. - Keeping your holding hand clear of the knife blade to prevent accidental cuts. - Swinging the blade through the cut, as this can lead to accidents. - Neglecting to change the blade when it becomes dull. - Never pull the knife directly toward you.

3. Which knife blade causes most knife accidents?

Contrary to what one might think, a dull blade actually poses a greater risk than a sharp one. This is because a dull blade requires more pressure to cut, increasing the chances of the knife slipping with force. A sharp knife, on the other hand, bites into the surface more readily, reducing the risk of accidents.

4. What is the difference between a carpet knife and a utility knife?

The primary difference between a carpet knife and a utility knife lies in the blade design. A carpet knife features an extremely thin and razor-sharp blade. Unlike the pointed triangular blades found in utility knives, carpet knife blades are square and less prone to snapping during use. This makes carpet knives more suitable for cutting carpet and similar materials.
