Back slitter knife....

Hi,

I came across this video where they use a "back slitter knife"....looks like a handy tool for removing just a section of backing paper.

Has anyone here tried this? Is it any good?

martin you may have saw mine on the uksb truck mate, there is two or three kicking about on there.
the ones i have are by murispec and if im right, i bought them a couple of years ago from papergraphics in glasgow, ask for david. they were originally for wallpaper seams.
they are very handy to have but there is a knack to them or you stand the chance of damaging the vinyl.

Robert, I could very well be wrong but I thought I could remember it from a thread about applying graphics using a centre hinge & how people cut the backing paper to start off.

I bought a couple of back splitters , one for large external graphics, and one for the workshop, slitting vinyl out of the cutter, very handy and my favourite tool, comes with spare double sided blades, for me it is a must have.

Is this any different from the cheap 'slitties' that are available from most of the sign material suppliers.

Alan, can't speak from my own personal experience but from what I have been led to believe yes they are different, I use a normal slitter & although it is great for slitting vinyl & backing paper it's not that good when you need to cut through just the backing paper when it;s still on the vinyl. I tend to peel the backing paper off the vinyl, cut it & then stick it back on again a bit further along so I have some exposed vinyl to start applying, these slitters prevent the need to do that.

OK Martin, that makes them a bit more interesting them as there are many occasions when that would be ideal.

Have you tried ordering one of these through the website??? Your £19.95 backslitter knife comes to near on £35.00 by the time they've added delivery, vat etc.

Yours

Not owning a backslitter knife anytime soon!

+ 1 for this tool. Got mine from Signgeer (JAG). Used it all day yesterday when fitting large graphics to a Luton. Perfect for slitting through the backing paper.

+1 from me aswell. The best I found so far but make sure you have spare teflon footers as they tend to wear quick and without them your tool can stop in the middle of cut :)

very true, i use a "dry" spray lubricant on the foot blade. originally used by Kodak for mounting large format media, which later switched by vehicle wrappers to aid vinyl application before the likes of bubble free medias where used.

I bought a guard knife on the understanding I could cut the backing paper only and not the vinyl when using centre hinge method, unless I'm just not practiced enough its not easy without damaging the vinyl as the vinyl just sticks to the shoe, bit of a disappointment. OK to cut vinyl and backing paper but a cheap slitty does the same job. :(

correct Alan, that's why i use the dry lubricant. it does take a bit of practice also as you can easy snag the vinyl during a cut. once you get the hang of it it does become a good tool. helpful in many ways and a damn site better than the shearing of the paper when done by hand, which many wrappers using them seem to think is just acceptable. :-?

Rob, I don't know much about the lubricant you speak of and I assume you spray it on the cutter shoe but doesn't it contaminate the adhesive of the vinyl when cutter slides through?
