Available Features and Options

S30V Steel

We consider this the absolute best blade steel available, and it is made in America. S30V contains carbon as well as high amounts of Chromium, Molybdenum and Vanadium. This steel combines fantastic edge retention and high ductility combined with corrosion resistance. Double-tempered - it can be hardened to a Rockwell hardness of Rc 59.5-61. However, it is difficult to resharpen yourself, but we do offer sharpening services for a nominal fee.

Great knife

The size is perfect for a first aid kit. It is thin and small and fits great in typical loops of an IFAK.

The Best

Everything in your description is true and more. I own and have owned many knives from hand made by masters to many of the major knife makers, but this little knife, I am always telling people, is with out a question the best knife I have ever owned.

Super Versitile Mini Knife

The Buck Hartsook Ultralite knife is a super all-around edc tool. It is perfect in situations where a larger knife isn't well received, like in an office setting. And it performs a variety of daily tasks superbly. Size: While I see the occasional complaint about the size, some even saying they were not expecting it to be so small. I am not sure why. Use a ruler to draw a 4"x1/2" box and that is about it. But don't let that small size fool you. Uses: I am currently building it a little leather sheath made out of some old reclaimed backpack suede. I used the Buck Hartsook to rip the seams of the backpack, cut off unwanted bits, cut the leather plate for the sheath itself, and now am using it to skive it. I use the Buck Hartsook to open packages, as a first aid knife camping, cutting veggies, and other tasks. It is just such a super useful, discrete tool that I am definitely getting a second. While the Buck Smidgen is identical in size I prefer the edge retention, overall strength, and corrosion resistance of Buck's BOS s30v. Sharpening: I really have had no problem getting and keeping the Buck Hartsook shaving sharp. It does take 5 - 10 times as long as 1095 cs but it is definitely doable. I only use a guided field sharpener. Specifically the fine diamond plate, medium ceramic and fine ceramic rods. The fine ceramic is like leather stropping other knives. I actually hope Buck keeps making this for a long time and that more people discover what a great xacto knife/box cutter/package opener/lunch box/first aid/leather tool the Buck Hartsook Ultralite is.
