Tamiya 74091 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.

I was a bit sceptical about this, but having tried other, not too easy methods of cutting perspex of acrylic sheet I decided to give it a go, and it has proved very successful. Simply score along the line to cut, not sure how many times one should score along the line but I ran the knife along four or five times; then bend the sheet over, away from the cut, until it snaps apart Produces a very clean break, and is effective on thin and thicker sheets, 5 mm being the thickest I have cut to date but no doubt it will do thicker. I've cut quite a number of sheets and not a single failure.

I don't know how I ever managed without this tool. It is really simple and quick to use.

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.

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.

So, I use plastic storage boxes as hamster cages - this requires cutting out the centre of the lid and replacing with caging. The first box I didn't have this tool and I went through 2 Stanley blades and 3 jigsaws trying to cut through it. It was painful and awful. So, for this time around I searched the internet to find this to be one of the only tools to suggest it works well with hard plastic. I can confirm that it is amazing and did the job perfectly! I didn't break my hands or any tools in the process! So if you find yourself needing to cut into storage boxes this is what you need (I was cutting into a 'really useful' storage box which is high qaulity). So yes, if you need to cut hard plastic buy it :)

i build model cars and found this great for deepening panel lines, and for removing parts like doors, hoods, or trunks, with more precision than a hobby saw could. sharpness, safety, and ease of use are what i wanted in a scribing tool, and tamiya quality delivered as always. what makes this tool a greater value than other scribes is 1) it's a two-way blade that you can either push or pull, and i've found use in both, and 2) the retractable, lockable blade is important for a paranoid safety freak like myself. i'm especially pleased with the durability; i've been using this for a year and a half and am still on my first blade. i totally forgot there was a compartment of two spares until i looked at the photo on this product page. tip for the novice: if you watch builds and tutorials on youtube, you'll see builders applying downward pressure when scribing. you DO NOT need to do this. it's sharp enough that simply gliding it along the channel will accomplish what you're trying to do. added pressure just increases the likelihood you'll jump the channel and scratch your model. easy does it.

「クラフトツールシリーズ」は、どれもとても使いやすくて、本品も当然重宝しております。 本体の形状などよく工夫されており、刃の動きも力加減も、非常にコントロールしやすいです。 極端な話、直線ならはじめに一回だけ定規でアタリをつければ、あとはフリーハンドでもいけるくらいです。 カーモデルの場合だと、ボンネットやドアパネルのスジ彫りに使用したら、「けがき針」のときよりもきれいに仕上がりました。 また、窓パーツのような割れやすい透明プラも、よく切れる分余計な力が加わらないので、ヒビの心配もなくきれいにカットできました。 逆によく切れすぎるので、プラ板をカットするときは必ずカッティングシートの上で行うべきです
