Product Description

Product Description

10 Pack, Rapid Edge Serrated Utility Knife Blade, Blade Fits All Standard Utility Knives & Has Been Tested & Proven To Provide Longer Blade Life Then The Competitors Blades.

From the Manufacturer

Now you can have a utility blade that cuts more evenly and stays sharp longer. It 8217;s like comparing an expensive steak knife to a butter knife. The unique, serrated Rapid Edge utility blade is available only from Rapid Tools. The secret behind the blade is its patented serrated design. It features three to five cutting surfaces as opposed to the single straight edge on all other products. No one ever goes back to regular blades after using the serrated edge. In addition to thousands of happy Rapid Edge customers, Rapid Tools can back up its claims with top-notch independ¬ent testing. The highly respected Bureau Veritas tested the Rapid Edge blade against six other leading brands on drywall, nylon rope, nylon carpet and asphalt shingles. The Rapid Edge was rated superior in resistance to dulling, blade wear and notch wear, and was the only blade with no visible wear after 150 cuts on the nylon carpet. In another study, hundreds of testers at the Handyman Club of America rated the blade no.1, with an astounding 95-Percent approval rating. Both professionals and do-it-yourselfers save a lot of time and money by using Rapid Tool 8217;s revolutionary blades 8211; which will fit in most standard knives.

Well, there's not a lot to say about some utility knife blades, is there?

In terms of construction, these are basic carbon steel blades. They're not titanium-coated and they're not bi-metal. A Rockwell test showed they're at 57 for hardness.

These blades are the same size and shape of a normal utility knife blade, except these are fully serrated. The blade is ground and sharpened on both sides, and the serrations are very purposeful. It glides through rubber, carpet, nylon webbing (like seatbelts or backpack strap), linoleum, and rope / cord with ease. However, if you use it on something like drywall or particleboard, it will gum up quickly. The blade held its edge well: about as long as a normal utility knife blade, plus another half.
Being the standard size, it was able to fit in any utility knife I have. The SuperKnife brand uses a contractor blade, which is thicker: if you're going to use this in a SuperKnife or the Gerber EAB Lite, then the blade will snap in but it will wiggle a little bit side-to-side.
The very tip of the blade isn't as needle-like as I'm used to in utility blades, but it's still able to pierce if you need it to.

If you need a blade that retains its edge through fibrous materials, this is a great choice. It makes a good all-around blade as well, but you don't get the precision you get from a straight-edge blade.

This does a very good job as a razor blade, but that isn't really what it is. It is a saw with razor sharp edges, and as thin as a razor. (because that's what it was born as...) They took a normal razor blade and ground fine serrations on the edge.

If you want perfect clean cuts, get a typical blade. If you can accept <slightly> rougher cuts, get this... But it's main strength lies in it's "sawing" ability. I had multiple layers of paracord wrapped around an item, tied tightly and then totally soaked (dry) with crazy glue. It wasn't going anywhere. A razor blade would have gotten through it, but it should have taken a bit of time. Using this blade with a sliding motion, it went through this effortlessly. It's not an everyday tool, but it SO does what it's supposed to do. Highly recommended. Highly - if this is what you want ands need.

Heavy cardboard... thick plastic zip ties... knotted plastic wrap - just as the title says. Great blade and a little scary how well they cut. It would be handy if they came in a re-closeable box, but a stapler takes care of that.

Ridiculously long-lasting, best freakin' razor blades I've ever tried. If you've ever gone from the original type to the gold ones, you know the upgrade that was. THIS IS 5 TIMES THE UPGRADE. The package is small (10 pack), but when you consider how long they last, 10 is plenty for a package.

I am a knife-aholic. I love knives. I have seen an increasing number of people carrying these folding utility knives so I had to try one out for myself. I figured for work they would be better than my usual EDC knives because they would hold their edge better and worked great for cutting bailing twine or breaking down boxes. Well I ended up hating the plain utility blades, did not hold an edge worth crap, would not hold an edge longer than a week when cutting down boxes.

Decided to try these out, Oh boy are they sharp! Hold an edge about twice as well as a plain blade (in my experience) and just work so much better for an EDC blade.

I work as a Carpenter, Electrician, and all around Stagehand in the Theater/TV world. These are now in my Gerber EAB as well as my standard mat knife, and I won't be turning back to normal blades. They beat normal utility blades across the board, from cutting zip ties, foam core, jute, muslin, etc. The serrations actually made stripping wires a breeze without proper strippers. Great little addition to the toolbag!

Makes easy work of the thickest cardboard boxes. Oil coated so they arrive in great condition. The serrated edge does seem to make a big difference in smooth cutting. Very little to no drag when cutting.

These blades are great, I work in a warehouse where I'm constantly cutting open and breaking down single to double walled boxes and these blades don't seem to dull near half as quick as others.

I've bought the Lenox titanium aluminum coated edge blades previously and felt as though I had to change them much more frequently than I expected, the 5 pack only lasted me just over a month.

I'll definitely continue to buy these blades, the serrated edge is nice and allows me to cut through double walled cardboard in one cut even after weeks of use. If your looking for a good reliable blade try these and I imagine you won't be disappointed.
