Emma Cook - The Tiny Turner - in collaboration with James Barry Sharpening have put together a kit suitable to cover your basic needs for sharpening both chisels and knives.
The reason behind this kit is to keep costs at a minimum, whilst providing you with good quality sharpening equipment.
The kit consists of:
1 x 8" by 3" Monocrystalline Diamond Whetstone*
1 x Set of 4 Diamond Needle Files
1 x Handmade 8" by 3" Double-Sided Leath Strop (for stropping/honing)
1 x 100ml Bottle of Lapping Fluid
1 x Tub of Mirror Paste (for honing)
1 x Piece of Anit-Slip Router Matting
1 x Tiny Turner Pencil
James Barry developed his diamond whetstones to be of the highest quality. They are monocrystalline - which are far superior to their cheaper, polycrstalline counterparts; and they are electroplated to their base block (which is produced to be as flat as possible) instead of being impregnated/glued on.
Both of these considerations give these diamond whetstones an enormous longevity advangate over cheaper alternatives. If you look after your stone it should last you a lifetime.
These diamond whetstones come with a 5 year guarantee as standard as long as they are used with lapping fluid to lubricate the chisels being sharpened, and not oil or water.
