All Smart Knives
Smart Knives
Smart Knives are NOT just blades.
And they are not "throw away"
You buy them only once.
Smart knives are designed to improve cutting accuracy and make plotter settings less complicated.
They are NOT imported from a far distant land.
They are designed and manufactured in UK by Edward Mathias & Co.
Smart Knives are combined blade and blade holder units.
Every blade arrives already fitted and pre-set in its own blade holder.
A Smart Knife replaces your blade and your blade holder in three simple steps.
Step 1
Remove your blade and your blade holder from your plotter
Step 2
Insert a Smart Knife.
Step 3
Start cutting.
Could anything be easier?
IMPORTANT - PLEASE REMEMBER
Smart as they may be they will not think for you.
A new blade or Smart Knife will usually cut at a lower pressure than the one it replaces.
You should always start with a low pressure setting and do a test cut.
WHY USE SMART KNIVES?
No need to take blade holders apart or fiddle with tiny springs - every blade is already fitted and pre-set in its own blade holder.
No need to remember what type of blade is in your plotter - noses are colour coded to indicate type in use.
No need to make fiddly adjustments - every unit is ready to use straight from the packet.
SMART KNIVES ARE NOT "THROW AWAY"
YOU BUY THEM ONLY ONCE
When they eventually blunt you return them to us for exchange.
We swap them for units with NEW blades already fitted and pre-set.
We also send you an addressed jiffy bag ready for your next order.
Don't throw it away!

WHAT IF YOU DON’T LIKE THEM?
Return them to us within fourteen days for a full and immediate refund.
Nobody who has tried them has ever returned them!
HOW THEY WORK
We preset the blade protrusion to expose a few microns more than the thickness of the range of materials the unit is designed to cut.
When your plotter is cutting correctly the coloured nose cap will run very close to the media but will not normally touch it.
If the knife force/pressure is accidentally set too high or if the media lifts because it is uneven or obstructed the nose cap will contact with the media and prevent excessive blade penetration.
Excessive blade penetration can jam media by pinning it to the cutting platen.
This is a major cause of damage to blades and cutting platens that can also cause expensive damage to plotters by straining cutting heads and other fragile mechanisms.
WHEN ACCIDENTS OCCUR (as they all too frequently do!)
Smart knives eliminate or substantially reduce the risk of damage to machines and materials.
Smart Knives are accurate, cost effective and incredibly easy to use.
If you don’t already use them you should try them.
We supply them to try on a “sale or return” basis.
We never get them back!
