Thanks Alex. I agree that good blades are difficult to come across in the UK. I've generally been looking at auction site, and am aware of the dangers of such. I picked up two Muromachi in good polish in koshirae and shirasaya last year, one of which was papered, for £1500 each plus commission. I was able to view before purchase, and both had been assessed by Bill Tagg. I suppose I should lift my Tanto budget towards £1000.
Thanks again
Frank
