OLFA SK-6 Fully Automatic Safety Knife with Blade Guard Honest Review

In this article we’ll be taking a look at the OLFA SK-6 Fully Automatic Safety Knife with Blade Guard and this will be my honest review of this utility knife designed specifically for user safety.

Ethic’s Disclosure:

OLFA was kind enough to provide the OLFA SK-6 Fully Automatic Safety Knife with Blade Guard at no cost for review. However as with all my reviews, I am not paid, sponsored, or obligated to give a positive review. This review is my opinion of the product based on my usage and knowledge and my review will reflect what I like and dislike about the product. I will do my best to provide you with an unbiased review.

My Thoughts:

What makes the OLFA SK-6 Fully Automatic Safety Knife standout from all the other utility knives is the integrated safety blade guard that protects the user from accidentally cutting themselves if the knife makes contact with a part of the body like an arm, stomach or leg.

The way the integrated blade guard works is that it activates and springs out only after the knife is no longer making contact with the cutting material. This ensures that if the knife makes contact with the body, the blade is surrounded so it can’t cut the user.

In testing the OLFA knife did exactly as described and only after it finished cutting cardboard was when the blade guard would spring out.

The safety features don’t end there as there is a slide switch that must be engaged by the user in order for the blade to protrude. If the user was to drop the knife after extending the blade, it would retract automatically so as to not harm anything. The only downside of this is that the user must hold the blade out at all times as it’s being used in order to cut and may tire the hand after prolonged periods of use. I didn’t find this to be an issue during my usage of the knife but then again, my job doesn’t require me to cut boxes all day long. 

Some might be tempted to tape the slide switch to keep the blade out at all times as to not tire the hand and this is not a good idea however even if one did do that, the guard would still spring out after making contact with the material. But it’s still not a good idea since the blade would be extended at all times and could still pose harm if the guard is not activated. The guard only activates AFTER the knife makes contact with material, not before.

Another safety feature is that the blade only sticks out just enough to cut boxes making this a perfect tool as a box cutter. This reduces the risk of damaging the contents inside a cardboard box.

The last safety feature is that the blade tips are rounded. They’re still sharp and can puncture into cardboard with ease but a rounded tip means that if it were to make contact with skin, it wouldn’t puncture deeply but would limit the cut to a surface cut.

The knife itself is well made and is very unassuming. It’s color scheme, lack of branding and simple bland design make it look like it came from a dollar store however it’s very well built and designed. Blade changes are simple with an easy to remove door to expose the internals. The only thing I’d like it to have to make an already excellent tool better would be if it had built in storage for extra blades. I would recommend this for anyone looking for a safety and quality utility knife that works great as a box cutter.

Great review. The only thing I would add is that you do not have to hold the slider out to keep the blade out. Once you start cutting, the force of the cut will keep the blade engaged while cutting.

Would love your thoughts, please comment.x
