Hi Dave,
The main chisels used for carving the maple leaf were 'Henry Taylor Super Sharp Set' palm chisels £37 from axminster for set of 6, i've had mine about 20 years now and still as good as the day i bought em,they are perfect for reaching the inside of bowls.The oak leaves were a bit deeper so used larger Ashley Iles gouges and Pfeil V tool and fishtail with mallet. I think the individual chisels are around £20 each

Also sharpening carving chisels is different to turning, i use a rexon bench grinder reversed with the guards swapped over so the wheel rotation is away from you, with a rubberised silicone carbide wheel for honing and a polishing mop the other side, Ashley Iles used to sell one but i did it myself for alot less, the kit for wheel and mop and polish is here-http://www.ashleyiles.turningtools.co.uk/sharpkit/sharpkit.html
Chris Pye uses wetstones, slipstones etc which is the best way of sharpening but it takes alot of time, the buffing wheel is fast but over time rounds off the corners.
The only other thing i tend to use is a 'Draper Rotary Tool with Flexi Drive' with the small milling tool to undercut leaves where access is a problem.
Paul, i have only ever used seasoned lime, from John Boddys or Mike Smethurst woodturning, seems very difficult to get hold of big noggins and expensive.
Hope this post is usefull and not too long, Thanks again for the warm welcome. Rob.
heres something else with leaves on.
