As a tribute to the entertainment legend keith Harris I have named by b3 butterfly Orville (might need to google it for younger/overseas members). Its certainly an ugly duckling! I took up the b3 butterfly offer and a bespoke voucher offer I had and with streakys help created the bat below. The idea is simply to design a small men's bat with the meat high up the blade and to pickup wonderfully well. Despite its slightly odd shape I think it does all of this.
Specs:-
38mm edge
65-66mm spine
Minimal concaving
Weight - 2'8.6
Density of cleft 380
Before everyone goes wow, I want one, I did a bit if cheating:-
Harrow length
Scooping in the shoulders and purist/TT shoulder droop
Very slight duckbill on the toe (can't even see it)
To keep it balanced and picking up well the spine is higher into the handle then normal, which also helps extend the middle upwards. I also wanted a lovely thick oval handle at the bottom and the spine blends in nicely. The middle extends down further than you think thanks to the butterfly stain. Tapping up its only the very bottom that sounds dead, that's fine as I don't hit much in the bottom area anyway. The middle is around 8-9 inches up the blade.
Could it be improved, yep, but I am looking forward to seeing how it goes before any future redesigns.
Many thanks to Dave and Streaky at b3 for answering all my questions and great customer service.
