We have had some strong winds recently in London which has brought down a
few dead branches from a large horse chestnut tree near my home. I picked up
a nice branch about 2 feet long by about 1 foot wide. I have a question.

Upon splitting the wood up with an axe I noticed that the wood was full of
knots. There seems to be no resin visible but is it still OK to use knotted
wood in the smoker?
