Tamiya74091 Plastic Scriber II

I recently bought some perspex sheeting for various projects around the house. I have not worked with perspex before so I searched online for the recommended ways to cut it.I had been thinking of using a jig-saw, but uncertain how clean or straight a line I could achieve.I saw this and ordered one. I have used it to cut sheets of thicknesses from 2mm to 5mm, and had no trouble at all. I scribe a deep groove and "snap" off the waste over the edge of a table or worktop. So far I have 100% success.It is easy to scribe repeatedly over the same line to achive the depth of groove that you want.I suppose I might have been able to achieve similar results with a stanley knife or similar modelling knife and a brand-new blade, but I am not sure.This scriber is easy to hold firmly - not too big or too small, and I find it sits comfortably in the hand.The blade slides out and back in again, and is locked in place with a simple screw mechanism, so no chance of it moving while it is being used (unlike some Stanley knives and modelling knives).The blade is thin, but rigid, and nice and sharp.The size and shape of the blade mean that it is a very effective cutter and does not flex as you use it - this is very important for scribing lines and repeating the same line.There are two spare blades safely stored in the handle, and held in place so that they do noit rattle around and dull their edge.

This tool is great for scribing plastic sheet and for doing panel lines on any model. I've used it loads and you get spare blades. It us very well made and well worth having.

The knife is of good quality.Its well made, quite tough and robust.The blade is a good width, not prone to bending and should last.The retracting mechanism is manual and the lock is manual also, but all works perfectly and smoothly.There is nifty storage in the handle for spare blades and this knife comes with one spare blade in the handle.I guess it depends on what you want it for as to whether it is any good.For me, I got this on recommendation that it would score (and remove) a thin groove of plastic from plastic model kits and thereby inscribe panel lines in my models.What this does can be replicated by a simple box knife or Stanley knife.It effectively just cuts a line in the styrene leaving a raised ridge - not what I wanted.If you are after something to make these marks or cut break lines in plastic sheets then a Stanley knife is just as good and probably easier to wield with force.That said, this is great for gouging out any filler that I leave in existing panel lines. The shape of the blade cleans out the existing line perfectly.As such, it is still a useful tool for me and is making light work of the hundreds of lines to clean up.

Brilliant and can’t recommend enough. I did get a cheaper one but after my third model I wasn’t happy with how clean the line would come out. I was advised to try the Tamiya one and was told it’s worth the money. 100% easy to handle and the lines look clean and sharp.

No problems what's so ever with this product.

This is one of those miracle model makers tools I'd heard so much about and finally decided I needed. Previously I used a self-modified Stanley knife hook blade with cutting angle ground to work as a scribe/cutter but it's a bit big & clunky although excellent for large work like acrylic/perspex glazing.This Tamiya Olfa cutter works okay but I found the thumb wheel clamping the blade too readily collided with my right hand holding my straight edge guide down - I'm left-handed you see. I can only use it if the straight edge is wide enough to grip clear of that thumb wheel.I took out one of the spare blades and found it fitted in one of my old craft knife handles with a collet-type blade grip. This works much better for me with more clearance to work.

Fits nicely in the hand, is comfortable to use and lets you scrible lines in plastic. A win I would say.

Really happy with this plastic scriber.I bought it to trim 1 metre lengths of UPVC at 2mm thickness to fit over a bathroom shower tray. I was really surprised how quickly I was able to achieve a straight cut with no burrs along the entire length. Well worth the money.
