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.



Olfa Utility Knives and Cutters

I’ve 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.
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.

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

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.

Olfa vs Standard Utility Knife

Knife Size Comparison to Exact Scale

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.”

  • Compact size takes up minimal drawer space, yet the bright yellow bodies are easy to locate.
  • 9mm snap-off blade refills have 13 blade segments to allow a fresh cutting blade in seconds without hampering work progress.
  • All models feature a stainless steel blade channel, no tool blade change, pocket clip and built-in blade snapper.

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 practical disposal containers to best accommodate your preference.
