OLFA Utility Knives – A Better Cutting Solution

Olfa Utility Knives and Cutters

Choose from the many utility knife and blade combinations to optimize cutting when doing crafts and home improvement projects.

I’ve used the typical utility knife for years, but at some point questioned whether there was something better, and with OLFA I discovered a brand of utility knives that offers many options and benefits.

  • At the core of all OLFA 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.

OLFA utility knives prove useful over a wide range of 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 allows the right combination for any task.

  • 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 possibilities from the Olfa project section.

Note: 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.

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.

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 and tool-less blade change.
  • A majority of the 9mm knives have a built-in blade snapper.

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

Safe Blade Disposal

OLFA offers several practical disposal containers.

An empty food container that won’t easily puncture, and has a secure lid, also works well for blade and sharp object disposal.
