Thanks, I cut the wood at work and just started carving it that night, the wood was worked green over a few days, to keep it from drying it was kept in a bag with the shavings.
Willow is good to work and as long as it doesn't dry out too fast its wont, or shouldn't split.
The knife I use is a one that I made, the blade is a Lauri drop point and the handle is mountain ash.
