Review: OLFA has a bigger and better selection of utility and snap-off blade knives

From crafts to home improvements, Olfa has a knife and blade combination to tackle your cutting projects.

I used the typical utility knife for years, but at some point questioned whether there was something better, and in my view there is. I discovered Olfa cutting tools, and unlike traditional utility knives, the brand has a slew of cutters to choose from; each one allowing me to better match a particular cutting need.

  • At the core of the utility knives is a stainless steel blade channel, which is wrapped in varied handles across the 3 different sized knife options.
  • Find a large range of blades. Use the knife you have grown accustomed to and comfortable with, yet be able tackle differing cutting tasks with a simple blade change.
  • Snap-off blades allow longer intervals between blade changes, and when the need does come to change the blade, you’ll appreciate the no tool blade change design.
  • Choose the knife and blade lock combination that best suites you. (i) Safety auto retract » blade automatically retracts when not in use. (ii) Auto-lock » quick and efficient blade placement. (iii) Ratchet wheel » allows the blade to be placed specifically where you want, and no worries of accidental bumping of sliders(auto-lock) and blade movement.

These cutters prove useful during many projects.

I put Olfa snap-off blade knives through numerous cutting experiments, along with using them on several of my own home improvement projects, and the range of Olfa knives and blades always perform amazingly.

  • Score and cut drywall
  • Score and cut foam board
  • Cut and trim plastic sheathing
  • Cut EPDM rubber gaskets
  • Cut rope to length
  • Find many more uses from the Olfa project section

Olfa doesn’t limit you to one size fit’s all.

The 9mm knives are ultra-compact and great for intricate cutting and package opening. These space-saving cutters are relatively inexpensive and so convenient that I have several of them throughout the house and garage. A minimal investment to always have a cutting tool on hand without wondering all over the house in search of.

The Olfa 18mm heavy-duty series offer a much lighter and slimmer body to the comparable standard utility knife.

Choose the 25mm knives for extra heavy-duty cutting.

Prefer the conventional style utility blades? Olfa has a selection of safety utility knives too.

Knife Size Comparison to Exact Scale

WARNING: Olfa doesn’t recommend extending snap-off blades past each blade score. When doing deeper cuts, use solid blades, which are available for 9mm and 18mm knives.

Standard-Duty (9mm blades)

OLFA describes their 9mm knives as “great for lighter cutting jobs such as packaging, shrink wrap, vinyl, window film, wallpaper, caulking, foam board and other materials.”

I find the 9mm knives to be the perfect lightweight, compact and safe cutting tool for purse and car compartment storage too.

Once the snap-off or solid blades are dull and no longer usable for cutting; OLFA offers several disposal cans to best accommodate your preference.

We also wrote about safe disposal of sharp objects that can easily be achieved with many empty food containers.
