The stone is not flat, especially 1000 grit side has a significant negative curvature in it's center, which doesn't allow to achieve flatness of the blade edge, while sharpening.

Cuts quick. Just overall great sharpening tool.

I am satisfied with the quality of this product.

Ich habe den stein über YouTube gefunden und habe nur gutes darüber gesehen. Jedoch ist zwar meine 300er Seite schön plan, aber die 1000er Seite dafür absolut gar nicht. Beim Ersatzstein genau das gleiche.Ich hatte ihn gekauft um damit meine Stemmeisen und Hobeleisen plan zu bekommen, sowie meine Japanischen Wassersteine zu begradigen. Das kann ich zwar alles machen weil ich dafür fast nur die 300er Seite brauche aber, ich habe ja nicht 115€ für einen einseitigen sondern einen doppelseitigen stein ausgegeben.

This stone is a kind of mixed quality:- I saw no surface tear out after some initial grinds I did. So the diamond bonding is good.- The flatness on the transversal direction (width) is quite problematic on both sides. The first two pictures show the 1000 grid side and the last one the 300 grit side. Looks like the edges of the stone are higher than the center portion.- The flatness on the longitudinal direction (length) is quite OK. The edges are a bit higher but less pronounced then on the transversal direction. No issue at all here.So if the tool width is max 50mm and it's kept in the center of the stone than this concavity is not a problem at all. But when flattening a tool that reaches the stone edges it will just transfer the concavity on that surface. Like when grinding a chisel's back side against the long edge.For this money I'm a bit disappointed but as said above it might be OK for some tools.

I ordered because I thought that at this price it would really be straight. It has a very clear curve, which really is not acceptable at this price.

Leider waren sowohl der erste als auch der Stein der Ersatzlieferung nicht plan.Zu beiden Seiten hin waren die Steine dicker als zur Mitte. Um zum Beispiel die Spiegelseiten von Stemmeisen abzurichten unbrauchbar.Auch lange Messer hätten keinen vollflächigen Kontakt.

Eine schöne große Schleifplatte zum Schärfen von Stemmeisen und Hobelmessern.Sehr gut in Verbindung mit Schärfhilfen verwändbar, da sehr lang und breit. Auch Große Stemmächste lassen sich schön schärfen.In der Lieferung sind eine Tasche und eine Unterlage für die Schärfplatte dabei.Zum nachschärfen auf der Baustelle sehr gut.

Affilatura rapida ed efficace. La grana è 300/1000 quindi non aspettatevi una cosa professionale ma per hobbisti va più che bene. L’affilatura risulta buona specialmente per legno dolce.

Perfecto para el primer afilado de cuchillas de cepillo o formones. Luego es necesario usar una piedra 6-8mil pero se gana mucho tiempo. Recomiendo usarlo con el líquido de la marca Trend específico para estas piedras de diamante

Muy buen producto ,se puede afilar rápidamente sin complicación

This is a good plate. If you have no others at all, start here and you'll get the most bang for your buck. The performance is very good.I have DMT, Trend, and Atoma plates, more than10 between the brands and the grits. The trend plate cuts the fastest, hands down. As somebody that has different types, I'll go so far as briefly explaining the differences that I see between them all. They are also advertised as having the most flatness of any of my diamond plates. Would I buy it again, yes. Having all of the different plates and if I could do it over again, I'd buy two different trend plates and then just move onward to my Shapton water stones. It would have saved a lot of money and I'd have still been happy with the results. I always follow water stones anyway. Be absolutely sure to use a rubber plate/stone holder to keep it in place and prevent the under-side from getting marred if you buy a double-sided plate.The gee-whiz comparison:The Trend is the fastest cutting plate that I have. It also has a consistent in the scratch pattern for the 300 grit side. Because it's double-sided, I didn't need to purchase two separate plates, less weight. The rest of my diamond plates are single surface and let me tell you, the entire collection is heavy. When using lubricating fluid, they work well. I don't have to apply fluid as much as I do with Atomas. Metal waste clears easily. These feel solid like DMT and overall best value. Could buy two different plates and get four grits. Best value.The DMT is a nice piece of steel, but the diamonds seem to fracture much more frequently and leave rogue scratches that are harder to work out. The DMT seem a tiny bit more susceptible to rust with a very faint reddish hue, even after using rust inhibitor in the lubricating fluid (hone right) and taking care to dry them with lint-free cloth as much as possible. When using lubricating fluid, The DMTs require the least amount of fluid and the metal waste clears easily. These feel the most dense and rugged of all.The Atomas are my favorite when I want a beautiful polished surface. With just a tiny bit more pressure, I can get mirrored finishes and the most uniformed scratch pattern of all. The plate is aluminum and the diamond plate substrate is steel, adhered to the aluminum plate. Atomas cut smoother and even though they are rated at 400, 600, 800, 1200, they actually feel like 600, 1000, 1500, 2000. I have to use lots of fluid continually as the metal slurry builds or the plate will dry and the tool will slightly stick. The steel substrate will gouge and scratch if you are abusive (I tested on one). The aluminum corners and base will ding and slightly bend if you drop it hard enough (tested too). These are lightest of all.If the steel is beat-up, I go to the DMT plates. If the steel is clean, I go straight to the Trend first because it's the fastest. If I need just the most gengle of touch-up work, I use Atoma. If I am putting a very good cutting edge, I then step through the shapton water stones up to 16000--depending on the tool--and will even finish on a stop that's equivalent to about 30,000 grit.

Great plate that was dead flat and came with all advertised materials. Pouch, slip resistant mat, cleaning block. Spent an hour or so flattening, sharpening and then stropping every one of my chisels, plane blades and pocket knives. Even a few kitchen knives. Combination of 300/1000 is perfect for getting an edge free of nicks and flat, then a few minutes on the 1000 to create a useable edge. Paired with a finer grit stone and a strop gets razor sharp results. I was on the water stone band wagon for a while, but the durability of the metal plates and the consistency of flatness really changed my mind. After a few long uses the 300 may wear a little to a 350 - 400 grit and the 1000 to 1250 or 1500, but it still works perfectly fine. I'm a carpenter for my work and I prefer this product!
