I think your wrong mate. I spoke to John yesterday and he makes every bat himself and chooses every cleft as well. He has made bats Flintoff and other legends and he is currently making for Matt Prior and 2 other England players. He has offered to fully make me 3 bats for a great price and I think ill probably take the offer.
I think you can see from the pictures that he has part mades there mate. Bit naive to think that he makes every single bat from a full cleft! There are many bat makers (from what I've heard) that have CNC shaped bats from TK, and theres no shame in that.
Having been to collect my bat from John at the workshop, I have seen the part made clefts dotted around. There's nothing taken away from what he does, he produces very good bats, and very good kit.
