Smith's 50364 Pocket Pal X2 Sharpener & Outdoors Tool – Yellow – Coarse and Fine – LED Light – Fire Starter – Signal Whistle - Compass

サバイバルナイフの太い刃には向きませんが 包丁と幅の薄いナイフはしっかり研げます。 カーバイトで荒研ぎしてからセラミックで仕上げ研ぎみたいですが粗研ぎで切れる様になるのでセラミックはあんまり使ってません。 包丁は普通の金属包丁ですがセラミック包丁には対応不可だと思います… 今まではカスタムナイフの研ぎはお店で頼んでましたがこれなら自分でも出来ますね。

I keep this in my processing kit in my hunting pack. Can’t go wrong.

El envío se realizó correctamente y llegó en perfecto estado. No se dejen impresionar por su pequeño tamaño, en realidad cumple con su función, los materiales con los que fue fabricado son excelentes. Me sorprende la facilidad de darle filo a los cuchillos y no sólo eso, además es silbato, tiene una linterna, ferroferio y brújula.

I keep it for use in my car

TLDR version: Buy it if you want a good sharpener and you are not a survival idiot. Don't buy this if you have an ultralight survival delusion as you will probably die. This little gadget is a fun design that employs many nice to have features into one compact design. The pull through sharpener is not a new idea and works on the principle of creating a small micro edge that can be quite sharp. The diamond round sharpener works well too for resharpening serrated edges and taking burrs off of a pulled through blade. I wonder why there are review here that speak to the ineffectiveness of this product. When you understand that this tool is not for putting a permanent edge on a tool but maintaining an already sharp edge that has been created by this tool, you really start to see the beauty of the simplicity of its design. Once you have made the micro edge with a knife you pulled through and this has changed your blade's cut style, you have to realize it's going to work differently than before because it's not the same kind of edge you were working with before. If you don't want to work with a micro edge that may well be different than the blades original profile, then this may not be your tool. If you know how to use the diamond sharpener rod to maintain the blades original profile, you're already set. If you realize how this works, how the different sharpening pieces work together, and are good with how that will effect your future cutting applications then buy this tool. I have three of these, one bought through Amazon. I have not had any problems with the functionality of the tool for its main purpose at all. Then again, I don't expect this tool to be a full professional knife resharping system that is going to put a laser edge on my knives. That is what a different and more expensive system is for. I also do not abuse my knives by making them do things they are not meant to do. For example, a knife like a Victorinox Tinker is not a pair of hard wire cutters and if you choose to try cut through something like that with it, well, I've got a sign for you that Bill Engvall would be proud to hand you. Likewise if you choose to use your knife tip as a screwdriver and break it or chip it, don't expect this little tool to fix your mistake of pressing a blade into service outside of its design of use. Moving on to what I consider bonus functionality, the survival applications. The whistle isn't the loudest thing out there but it's better than screaming and less energy and voice consuming. There are purpose designed whistles that do a better job and yes you should probably carry one. The small flashlight isn't really that bad, not the most amount of Lumens I've ever seen but it is a handy little light for searching around inside backpacks or boxes in the dark. If you're relying on this light for all your illumination needs and trying to go Ultralight, you'll be in the dark in short order. You'd be better off with a headlamp and a Maglite Solitaire Led on your keychain. When it comes to flashlights, the rule is two is one and backup batteries are a thing. This light was never meant to be a full time use light but merely a nice to have option for the limited time it may work. Not a deal breaker in my opinion. If I want to buy a flashlight, I'll buy a good sturdy flashlight. I didn't buy this for illumination, I bought it for sharpening knives which it does well. The compass is functional on all three that I have and works just fine, if again you understand its limitations. It's never going to be a military lensatic compass that is built like a tank and this little guy will be more susceptible to breakage or loss because of its size, design, and attachment method. Moving on to one of the most well executed parts of the whole tool aside from its main purpose, the fire starter. It throws a lot of sparks and is an excellent backup to your primary firestaring means and/or kit. Why a backup? Because of the fact that the flint stick itself is smal and thin and thus prone to breakage. It will not put forth sparks as long or as reliably as a dedicated 1/2 diameter by 6" long ferrocerium Rod that is predrilled for a lanyard attachment. I would wager that many individuals didn't even read the product information packet instruction manual that came with the tool that shows you how you're supposed to use the striker with the pull through sharpening carbide section to throw those sparks and likely already broke or will break their tool because they screwed up; likely blaming the tool for their own failure to do their due diligence in knowing their equipment ahead of time. Folks, we have to realize that the products we buy have limitations and specified areas of use. We must be able to understand those use areas to employ these tools with the right mindset so that if we must use the tool outside of its designed functionality we can do so safely in knowledge of the fact that we may need to MacGyver a different approach to something more workable. This little sharpener works well when you completely understand it's limitations and you have taken the necessary precautions to only have to rely on the survival applications in the most dire of situations. Translation, if you're looking for a survival panacea from this tool, get a reality check. If you're looking for a good sharpener with some bonus backup survival functionality, buy this tool.
