Sharpening knives

[theNude]

Howdy,

So about a month or so ago we picked up a set of global knives same as link below

http://www.cooks-knives.co.uk/acatalog/Global_G-888_K__8_Piece_Knife_Block_Set_-_Dotted_Block.html

I want to keep them sharp but i am aprehensive about going at them myself, can you get someone to sharpen knives for you? or is there a good tool that can do it for me so that I don't ruin them?

thanks for any help.
