Description
The Yato snap-off knife 18 mm with rubber body and slide lock is a utility knife with an 18 mm snap-off blade for cutting packaging, cardboard, plastic film, carpets and insulation. The body is ABS plastic and the handle is covered with a soft TPR anti-slip coating that keeps its grip even with wet hands.
The blade moves in a metal blade guide that keeps the blade straight and stops it wobbling when cutting. The blade position is locked by an automatic slide lock (auto lock): the blade stays in the chosen position without a separate screw and withstands up to 20 kg of pushing force before slipping. The lock prevents unintended movement of the blade both outwards and inwards, so the knife also suits cutting thick materials and narrow grooves where the blade can get pinched.
The blade is SK5 carbon steel that stays sharp for a long time. When the tip gets dull, snap off the dull segment and carry on with a new sharp edge. The knife takes standard 18 mm snap-off blades, for example Tajima snap-off spare blade 18 mm blades. For thicker materials, the same range offers the Yato snap-off knife 25 mm.

Yato snap-off knife 18 mm instructions for use:
Push the blade out with the slider only as far as the material being cut requires, usually one or two segments. The slide lock holds the blade in position automatically. Cut by drawing the knife towards you with an even movement and keep your other hand outside the cutting line. Cut thick materials with several light strokes rather than one forceful one.
When the tip gets dull, push the blade out by one segment, grip the blade at the snap line with pliers or a snapping tool and snap the segment off. To replace the whole blade, remove the back end and pull the old blade out; insert the new blade into the guide with the bevelled edge forward. Push the blade fully in for storage and transport.
Warnings:
- Sharp blade: The blade is extremely sharp. Keep the blade retracted when the knife is not in use. Never cut towards yourself.
- Snapped-off segments: Removed blade pieces are sharp; collect them and dispose of them in metal collection or in a closed container.
- Do not use as a lever: A snap-off blade can break under sideways load and fly off; do not use the blade as a screwdriver or a pry bar.
- No electrical insulation: The knife is not VDE insulated; it must not be used to strip live cables.
- Protective equipment: Wear cut-resistant gloves and, if needed, safety glasses. Take a damaged knife or blade out of use.
Frequently asked questions (FAQ):
What does the slide lock mean on the Yato snap-off knife 18 mm?
The blade position is adjusted with a slider, and locking happens automatically without a separate screw or wheel. According to the manufacturer, the lock withstands up to 20 kg of pushing force, so the blade does not retract when cutting thick materials.
Which spare blades fit the Yato snap-off knife 18 mm?
All standard-size 18 mm snap-off blades (18 × 0.5 mm), whatever the manufacturer.
What does SK5 steel mean?
SK5 is a Japanese carbon steel grade commonly used in snap-off blades. It is hardened, so the blade stays sharp longer than with softer steel grades.
Is the knife suitable for left-handed users?
The slider is on the top of the body on the centre line, so the knife can be used with either hand.
