Question: Is it bigger then a iphone 4?
Document: This knife is a great little knife. I have 4 of them, 1 for me, 1 for my wife, and 1 for each of my sons. My wife carry's hers in her purse. The knife is small so it is easily carried in your pocket and will not be noticed. I use it as a backup to my typical pocket knife. The knife is exactly as described in the description. I highly recommend the knife to anybody who wants a small knife that is not cumbersome.
the knife is the size i need . its a thinner blade. the only complaint is the blade isnt folding all the way closed. but there is a life time warranty so i cant say anything bad really
the knife is fine, but it is way too small for a man's pocket knife. I will give it as a Christmas gift to my grandson.
the knife had rust/stains on the blade and in the handle, the quality of the steel is questionable, the numbers weren't stamped all the way on the blade. This is NOT the BUCK that we've come to know and love.
small and easy to use looks good and it stays sharp for a long time. this is what you want in a knife. I have bought several and lost several but would buy another.
i love Buck and intend to keep collecting them lol this Little pocket folder has the durability of all of its larger cousins and is worth much more than the price i paid.. i will have this for a very long time i think assuming it doesn't get stolen
brought back fond memories and recommend buck to anyone, thanks for the memories. This pocket knife is all I have wanted and has stood up to the test of time
You should never leave home without a small knife like this in your pocket. I recently ate in a restaurant which had no knives to offer. I whipped this out and was cutting fish and metal tarter sauce packets open as easy as you could want. The Buck site is here.[...]
Yes, it's an American knife made in china. Does it affect the performance of the blade? Nope, came sharp and ready to go.
Was very disappointed when this arrived and saw that it was made in China and not the Buck knife mfr. in the U.S.
Answer: no
