This will most probably appeal more to the UK contingent.
I have just taken delivery of a set of 10 Soba (made in India) cutters, being sold by Chronos.


On closer examination, they seem to be very well made, and I certainly feel, well worth the 30 squid I paid for them.
Not only can these be used for cutting half moon woodruff slots but also full length slots in shafts, and also, used in conjunction with a normal end mill or slot drill, can be used to cut t-slots as well., as long as you don't penetrate too far down.
I can see a few bits of tooling being made that I couldn't do before with any ease.
