Safety knives cut most general industrial materials with ease. Safety knives never make a cutting task more difficult, they just make it safer. Usually if it's difficult to cut with a safety knife it was difficult to cut with a dangerous fixed blade knife too.

Fortunately this is rarely the case because safety knives can actually make the cutting task safer and easier at the same time! The brief videos below will emphasize my point. Each one is just over a minute long and can go a long way to dispelling myths about using safety knives.

Corrugate - Trigger style safety knives have made engaging the blade a breeze:

Box tape - Frequently cut, never easier than this!

Shrink wrap and strapping - Concealed blade knives hold the cut better than exposed blade knives and protect the product too!

Cutting bags - Previously known as a difficult task until modern concealed blade knives and long blade safety knives were developed:

Insulation and foam - Again, formerly known as a difficult task until modern safety knife designs hit the market:

I hope the videos above help you realize a total safety knife program is easily attained.

Thanks for your time and have a safe day!
