Brilliant little corner cutter
Great quality corner cutter which cuts evenly and cleanly though paper and card stock. Just used on some 220 gsm paper to round off the edges on print and play cards I printed. The cutter is small and easy to store and gives your cards a professional look and feel. Well worth the purchase and highly recommended for crafting projects.

Solid little piece of kit.
Was shopping for a card corner cutter and was tempted to go for a chaper option, but was weary of inferior products. Searched around a bit more and came across this Sunstar Kadomaru Pro, Corner Cutter. The reviews were good, and it seemed like a good product. I took the plunge and was not disappointed. I needed it to make some dividers for cards in a board game. It was easy to use, and even quite thereaputic. I can't rate cheaper products, but if you're looking for something solid and well built, this is well worth the money.

Great device for creating rounded corners
Brilliant little device for creating rounded corners on paper and thin card. The three sizes of cut offer a nice range selection. Good build quality and weight gives a quality feel to the cutter. Very easy to use and well worth the money. Highly recommended.

High quality mostly accurate
Bought to replace a cheap flimsy corner rounder that just chewed up corners, this is a much better quality cutter. It does 3 rounding sizes and I have found it mostly easy to use, however I have found that the Medium corner profile, which is opposite the handle is inclined to jam and to fail to cut as reliably or accurately as the other 2 profiles, which is the reason for only getting 4 stars. I am usually rounding the corners on sturdy cardboard, and this cutter would have no issues at all with thin card and paper. I am happy with it and tend to use the small or large profiles to avoid any issues when cutting thick card. The price reflects the quality of this item, and having tried and failed to use the very cheap versions I considered this a worthwhile investment. Overall I would recommend this to anyone who regularly rounds corners. This is very useful to have as someone who makes ATCs several times per week and so uses it dozens of times most weeks.

Best Corner Rounder By Far
This is the star of corner rounders. It's very good on standard card stock, but I wouldn't overdo it and go to a very thick card stock. It does the job and it's very easy to use.

Excellent Piece of Kit!
This made a job I was dreading - rounding the corners of 324 promotional cards - a relative breeze! And what's better is there were no miscuts resulting in wasted cards, thanks to the really positive cutting action of the machine and firm card seating jig. I was half expecting the machine to blunt when doing well over 1,000 cuts on the same 5mm cutting section but it didn't. I'd heard good things, but at this low price point the machine surpassed expectations and much better than my X-Cut corner rounders I've been using for years.

Quality corner cutter but for light - medium craft/hobby use
Variously described as either as a ‘corner cutter’ or ‘corner rounder’, the Kadomaru Pro from Sunstar is a beautifully constructed item, made from quality plastics and a tactile delight to use, with its distinct and satisfying 'click’ every time a corner cut is made. It is clearly designed to cope with small craft projects only. It offers three sizes of corner cutting: 3mm radius (small); 5mm (medium) and 8 mm (large). Rather cleverly, the plastic press lever on the top is not only moulded to show the indicators S, M and L but also the actual shape of the cut, so that you can have an entirely accurate idea of the shape of the corner cut being applied to the paper. In terms of what it can deal with in one cut, I'd say it can cope with up to about 4/5 sheets of 100 gsm paper a cut, but anything over that I think that would be pushing it, if you want a clean cut. Overall, an excellent corner cutter for light hobby or occasional use. If you want a heavier duty corner cutter, then look elsewhere. For example, something from xcut, dogcraft or we are memory keepers, however, you will need to spend at least about three times as much, i.e., in the region of £30+. If you want a really heavy duty corner cutter, then I suggest consideration of a product from postroom-online.co.uk which sells some truly monstrous manually operated industrial/professional corner cutters, but be prepared to spend in the region of £100 or more!

AMAZING teacher gift!!
As a teacher who seems to cut and Laminate endlessly, this has been my favourite tool! It cuts clean, curved corners through multiple sheets of paper/card and through laminated work! Can’t fault it yet!! Brilliant for any teacher!

Cet outil est très pratique pour obtenir des angles arrondis parfaits, il propose 3 tailles différentes et permet de découper du papier de 80gr comme du papier de 180 g avec en plus l'épaisseur d'une pochette pour plastifieuse thermique. Je m'en sers très régulièrement pour faire des photocards, des stickers, ainsi que des charms en plastique rétractable, et je n'ai aucun problème d'usure à ce jour. Je suis satisfaite de cet achat et je le recommande à tous ceux qui recherchent un résultat impeccable et rapide pour leur projets.

Me gustó el producto porque no es caro y es de calidad, comparado con las otras opciones que hay en la búsqueda. Además corta bien hasta 3 hojas.

Easy to use corner rounding machine with convenient lock function. Smooth lever mechanism makes it a breeze to make nice round edges. Works even with thicker card stock. Advantages: • 3 corner radius options: 3mm, 5mm, 8mm • Internal lever mechanism = low force required Mine didn’t come with a hologram sticker in Australia. Seems this is to avoid counterfeits in the US and Europe only.
