Not my subject really. I thought i was just goona get to rip into to some geeky crow who has more knives than a homocidal Ninja. Oh well next time aye!
Go for the mixture of the two. Gerber and leatherman are the shit n u cant go wrong. & i have a sharpner on a key ring. No art to it its in a V shape and u just run the blade over it 10 times or so. I'll check my kit at some point n let u know!
if you are using folders like the one above, a simple "v" knife sharpener like the one mentioned above should do the trick. If you wanted a real professinal job you can use a wetstone of various consitencies and an set angle.
Different blades are suited to different jobs, you haven't stated for what purpose you want to use the knife, also bear in mind the implications of carrying a blade over 3.5 cms in a public place (can be classed as an offensive weapon).
Hehe! I caused a whoopsie. Its okay to be a Knife collecting 15 year old mate dont worry about it. Its just a shame your probably a 35 year old singley!!!
Nah on a serious note what he said was all furry scruff imfo so u cant go wrong. Oh and as for the legal position the 3 and a half centremetre thing is bollocks. it used to be the and a half inches but it is illegal to carry any bladed article which you cant justify having on your person under Section 1 (9) PACE act! 1984
The CRKTs (columbia river, knife, tool) are nice, I have one, and with a 3.5" folding blade its hardly ramboesque. Spyderco "clip-its" are also very good.
Basically, a small folder designed for one handed operation should be all you need, and I use a pocket "kitchen devil" sharpener to maintain a keen edge.
Off course, for some people, a pair of round-nosed plastic scissors and adult supervision are more appropriate.
