鹿の解体に使うナイフに毎日使っています。自宅でも職場でもナイフケースに入れて持ち歩けるので重宝しています。YouTubeでどこかの国のシェフさんかな、研いで絶賛されていてカードの使い方を見ることが出来ます。 毎朝、家を出る前に、ナイフをこのカード3枚で研ぎ、革砥で整えています。

Eu tirei foto dele embalado, mas já foi testado. Ele é do tamanho de um cartão e cada um vem dentro de uma capinha com cores diferentes, porque cada um é diferente.

I have a heavy duty French mandoline slicer and didn't want to have to buy a new piece because the cutting edge became dull. This small form factor sharpening tool did a quick job of restoring my edge. Best part is that it's compact enough that I didn't have to take the mandoline apart. I keep this in my knife drawer now.

Rápido afilé con el set un cuchillo higonokami que por accidente le arruiné el filo con un afilador V-shaped chino barato que x curioso compre y con las tarjetas diamantados restauré el filo y pasó de nuevo satisfactoriamente la prueba del papel "térmico" ( yo pruebo mis cuchillos y navajas con las notas emitidas del super que son de papel térmico más delgado y un poco más flexible). Contento con la compra y con la facilidad con que recuperé el filo del higonokami.

First of all Excellent Product. They are truly credit card sized. Product Review. How to Use: They are the size of a creditcard, and on the back side of the plate is a sticker that tells you the stones information. Blue says: D3C: Coarse, 45 micron (325 mesh). Red Says: D3F: Fine, 25 micron (600 mesh) Green Says: D3E: Extra Fine, 9 micron (1200 mesh) Under that is the DMT logo with their phone number and website address. THe sticker is clear with the letters in the color related to the identification of the stone mesh. When you hold the sharpening stone plates you can feel the weight to them and if you lightly run your fingers over the sharping side of the stone you can feel the coarseness of the stones. You can also see the diamonds shining on th coarser stones the Blue and Red, as where the green coded plate the extra fine it looks like a piece of polished metal. BREAK IN PROCESS: To break in your stones use a cheap knife if you want I did. you may see little discoloration spots on the stones and trust me, it does nothing to the stone. They still sharpen your tool. It does not take alot of pressure to get these diamonds to cut. I use the amout of pressure on my stones as you would just resting your hand down on a counter relaxed. People saying they when they sharpen their tools or knifes with these stones and the diamonds are coming off, that is because they are pushing too hard. Rarely would it be a product defect. SHARPENING PROCESS: They say you do not need to use water or oil. I get my stones lightly wet with some water before sharpening. The reason is the water on the stones else collect the loose shavings so you don't have to worry about them in the cleaning process. To hand sharpen a knife for example, you can hold the stones in your hand and while *PAYING ATTENTION* sharpen your knife quite easy with out cutting your self. The way I hold the stones is the following. Follow these steps. (wish i could upload photos) Palm up hand open take your ring middle and index finder and put them together, if you have small hands use ur pinky too. Now your thumb you can brace the corner of the stone if you want but you wont need to because you will not need to use alot of pressure, hence the stone wont slide around on your hand. The weight of the stone will be enough to rest in your hand or on your fingers with out it moving around. Now I don't wear gloves while sharpening knifes and I know I should for stones this size and because they are being help in my hand. Yes I can easily cut my self, but I like to feel the stone in my had and I have the experience. For this review I am going to advice you to wear some sore of protective leather gloves, just for my own peace of mind so if you loose concentration or slip you don't cut your self. It requires little pressure and just go slow. one pass should take 2-4 seconds. Do not go fast go slow and steady. Start with the blue stone, then the red stone then the green stone. For touch ups on knifes green or red may be enough. For some good re beveling blue is needed or if it is really dull. If you have to do allot of re beveling and deep shaving these are not the right stones for you. Look into the DMT Dia Sharp 8" Stones. They come in all 6 grits. These are for on the go or even at home simple and quick sharpening. For any big projects like a busted tip knife, super bull knife you need to look into the DMT Dia folds and or the DIA sharp stones. I do say the 8" DIA sharp stones because they are the only size in all 6 Grits. from Extra Extra Coarse to Extra Extra Fine. CLEANING: To clean your stones simply run them under water and get a soft tooth brush from the store and lightly scrub them. the water and the tooth brush is enough to get the metal filings out. Do not use a SOS pad or a metal wire brush Why you ask? 1. these stones will cut the metal from the brush and just embed more metal into them. 2. You can scrape off the diamonds if your pressing really hard. All you need i a tooth brush and some running water. Now for some harder cleaning you can use some commet or dish soap. If you do not press super hard on these stones and use light pressure and rinse/wash them after each tool you clean you wont have shaving deeply embedded in them. I will sharpen 1-3 knifes before cleaning. STORAGE: For storing these stones, please make sure the are 100% dry. After cleaning them as mentioned above you need to dry them. do not rub them dry with a paper towel or a towel. Simply pad them dry. If you want use a hair dryer after padding most of the water off or a air compressor and lightly blow off any extra moisture. Place them back in the corresponding sleeves. I put my stones with the cutting side facing to the colored side of the holder. The reason is the transparent side is a bit short and you have a chance of your stones being slightly exposed and I would rather have the back of the plate corner exposed than the cutting front side exposed. Finally I would recommend these stones to anyone who wants to keep and maintain their tools properly. They are the right size for travel. If you are a prepper they are truly pocket sized and the size of a credit card. It is worth to but this combo pack and not the individuals. You truly use all 3 stones. If you have the bigger bench stones you should still get these. They are small enough and would be perfect for a hunting/fishing tackle box. They will NOT sharpen Serrations. For that you need the "Diafold Serrated Knife Sharpener". I would recommend that you buy all three variations of those as well. I wish these came in Extra coarse and Extra Extra fine. Maybe in the future they will come out with them in those styles. With enough pressure from consumers they will have the incentive to make them. If there is a demand there will be a supply as the person from DMT told me on the phone. If you are ike me and want the 12inch Magna Stones or the "Diafold Serrated Knife Sharpener" in all 6 variations of mesh please call DMT and tell them. They need to know they there is a demand for them before they will make them. I hope this review was helpful if so please click like and comment if you wish. IF it was not helpful please leave me a comment telling me what was not helpful and what information was lacking and I will be more than happy to add the information to the review. Have A Wonderful Day!
