Description

The Atoma Advanced Diamond Sharpening Plate #400 Grit is a versatile tool designed to flatten dished whetstones and replace traditional whetstones up to 500 grit. It offers the perfect balance between coarse and fine grit, making it suitable for a wide range of sharpening tasks.

Compared to traditional whetstones, the main advantage of using an Atoma plate is its ability to remain flat over time, providing consistent performance and longevity. The Atoma #400 is a staple grit for general whetstone flattening, covering a range from low grits to high polishing grits.

To use the plate, mount your whetstone in a stone holder and rub the Atoma plate on top of the whetstone in various directions until the stone is effectively lapped.

Atoma Diamond Sharpening Plates are products of Tsuboman, a highly regarded Japanese manufacturer known for their refined diamond products. These plates are made of mono-crystalline diamonds with a cutting abrasive surface mounted on a 10mm thick stainless steel base. The base is machined to be extremely flat, ensuring the diamond plate remains flat throughout its use.

The quality and durability of Atoma plates are among the highest available on the market. They feature precision-made surfaces with high uniformity, maintaining their flatness even after prolonged sharpening sessions. The diamond plate can be replaced after a few years without purchasing another baseplate, as they are adhered using strong double-sided tape.

Atoma Diamond plates can be used dry or with water, depending on personal preference.

Another great bed frame from Zinus
Size: Queen, Style: Leah
This is the 3rd or 4th or so Zinus bed frame I've purchased and just like the rest, the assembly is easy to follow, it's sturdy, and it looks great. They're also easy to break down and re-assemble in case of a move. The way they use Velcro for the slats to stick to the frame that otherwise ALWAYS fall at some point on other bed frames and is a pain to fix, makes it so much better. They also have a sticky thing on the slats to stick the mattress to the bed frame so the mattress doesn't slide around but I never need to use it. I assembled the bed frame by myself and it took less than an hour. I love that they include a little ratchet in the hardware. All the screws screwed in easily to all the places they needed to go. It's not too heavy. I have a 12 inch mattress so it does almost completely cover the bottom slat on the headboard. The pillows on my 12 inch mattress pretty much cover the headboard. They must use a really thin mattress for the product picture because my bedding engulfs 99% of the frame and you can barely see it, so be warned if you want the bed frame to be visible but have a high mattress/fluffy bedding. I got this one because I had a really low profile frame from them before and I wanted to utilize under bed storage. This has plenty of room to put things away underneath. Either way I really enjoy Zinus's products and will continue to purchase them in the future.

Nice bed, directions need improving
Size: Twin, Style: Leah, Size: Twin, Style: Leah
The assembly should have been so simple. But because of the directions using letters instead of numbers and the product pieces being identified with numbers not letters, it yielded confusion. What should have taken 30 minutes ended up taking over an hour with more head scratching than there should have been. Overall great piece. The box was severely damaged upon arrival and was taped up poorly. A few pieces fell out of the big hole in the box and got knicked up when bringing inside thebhouse...not worth returning over, but still unfortunate for a nice bed. All said, the bed looks nice and feels sturdy for my toddler.

Solid Frame – Worth It, Just Be Patient with Assembly
Size: Full, Style: Kai
Long Review:
 Surprisingly solid bed frame—well-designed and very sturdy. The packaging was slightly damaged during shipping, but luckily the frame itself was untouched. The included ratchet tool was a lifesaver; tightening all those bolts gets tiring fast after the fourth or fifth piece. The instructions could use improvement. The printed manual uses letters for parts, while the frame itself uses numbers—this mismatch makes it a bit confusing at times. The numbered stickers are helpful, but without labels on the parts, you’ll have to rely on grouping them visually and cross-checking with the paper guide. Assembly doesn’t require much brainpower, but the most frustrating step was attaching the backboard. I recommend leaving all the bolts loose until everything is aligned; trying to force the bamboo headboard into place can lead to misalignment or even damage. TL;DR: Great bed frame, sturdy and simple to assemble. The ratchet tool is super helpful. Instructions are a bit confusing—but better than IKEA's. You got this!!

Looks great, not quite easy to assembly.
Size: King, Style: Leah
Mostly easy to put together. Instructions and it's labeling of parts was a bit confusing, but if you pay attention to orientation of parts and where the holes are at in the photo, you'll get it. We've been sleeping on it for 2 months now. No problems at all. Seems very sturdy and no creaking or squeaking. One bolt inset was stripped and wouldn't take the bolt (left middle crossmember) but with at least 1 in it, it's working fine. It's not load bearing really so it doesn't matter.

Very nice!
Size: Twin, Style: Leah
This bed frame is fantastic, and was a lot easier to put together than some of the reviews would have you believe. The instructions were good, and the pieces of the bed were labeled with stickers to make it easy. It even came with a little ratcheting Allen wrench that made things faster. The bed doesn't wobble to creak, it looks nice, and it was affordable. I am very happy with it and I think that you will be too
