I've been looking into getting a hone, but Norton's seem hard to get here in the UK and are fairly expensive.

I came across this Grunwerg 3k/8k whetstone on eBay: http://www.ebay.co.uk/itm/110905021720?ssPageName=STRK:MEWAX:IT&_trksid=p398 4.m1423.l2649

It is intended for kitchen knives, but would it be fine for honing a straight? Anyone else used it by any chance?
