Im constantly picking wood up, and have a little wood pile in the back garden, in a metal dustbin, and will occasionally carve one from there.
It really is satisfying.
The trick is having a good socket for your hand. Bone, a nice colorful rounded pebble and put your own hole in it, a shell, a shotglass, and just carry that around with you.
Its very easy with a decent socket to press down with.
Ive been using one of the yew jobbies with the steel bearings in it, for the last few weeks, which is very easy to get an ember with. If youre having difficulties, nothing wrong with buying a socket, and using it. Just collect the heartboard and drill, and bow from your local wood.
[And if youve got an audience, they dont need to see the socket youre using.....] Just accept their plaudits as you whip up an ember in seconds.
This is the one Im using at the moment. An ash drill, pine hearthboard, [1/16th of a trunk, split down with the sfa] scots pine bow, paracord shoelace.
