想像以上にちゃんと研げるうえに面直しの手間もなく水も油もいらないのでフォールディングナイフを研ぐのにとても使いやすいただ、こんな番手の高いシャープナーなんて外で使うこともないので、携帯性よりも使いやすさ優先でハンドルは付けてほしかった、とりあえず革砥の板にスポンジで固定して使ってるそれを差し引いても評価は星5

Se trata de una piedra muy recomendable para llevar en salidas. Funciona muy bien, está muy bien hecha y la funda es excelente.

Very nice stone and works well, fine grit is good for a sharp polished apex.

Much better than the DC3 I had before this, more consistent over the diamond plates they have. Mine came with a small chip on the edge of the white side but it still has a very workable space even for kitchen knives and axes if you want a quick service before carving. Even with the 0.1 micron stated grit on the white side I always recommend a strop to eliminate the burr and bring out the real polish of the edge that it can bring. With this stone I can get my good knives to hair popping sharp and even my cheap beater knives well maintained to handle anything I need them for. I've taken this with me to work in a kitchen and even family parties to quickly touch up knives to make prep and carving go smoother, especially when it's not well looked upon or there is no time to give a proper service to whatever tools you need to use

Used this to rehone some knives i have used (each knife failing the fingernail test) and within 5 minutes of sharpening each knife with the cc4 it was more than shave worthy which if you are in the field is more than good enough.I nornally use whetstones to sharpen and rehone my knives at home then when they need a touch up ill use this cc4 if im out in the woods and for it only weighing 77 grams (cc4 weighs 52 and the leather cover/strop is 25g) i dont think theres another knife sharpening system this light, compact and effective anywhere else on the market.Ive used this to touch up fishing hooks, arrowheads, scissors, knives, scalpels, straight razors you name it.Would i use this over a set of whetstones?Yes and no, if at home ise the whetstones for a much sharper cutting edge but if you dont have the time, money, space or the interest in getting a fancy knife sharpening setup which can take a lot of time and effort to learn how to use consistently then the cc4 will more than suffice but dont expect to get reality splitting levels of sharpness, it will create hair splittingly sharp blades but thats about it.
