Persimmon is very hard to season because of loggerhead worms, knot-release splitting that can go full length of the bole, discoloration, decay, cupping and warping when dried after milling, and of course, checking. The only way to prevent all of the above is to properly cure the wood in log form.

In North America, the lightly colored, fine-grained wood of D. virginiana is used to manufacture billiard cues and textile shuttles. It is also used in the percussion field as the shaft of the Tim Genis Signature Timpani Mallet Collection. Persimmon wood was also heavily used in making the highest-quality heads of the golf clubs known as "woods" until the golf industry moved primarily to metal woods in the last years of the 20th century. In fact, the first metal woods made by TaylorMade, an early pioneer of that club type, were branded as "Pittsburgh Persimmons". Persimmon woods are still made, but in far lower numbers than in past decades. Over the last few decades persimmon wood has become popular among bow craftsmen, especially in the making of traditional longbows. Persimmon wood is used in making a small number of wooden flutes and eating utensils such as wooden spoons and cornbread knives (wooden knives that may cut through the bread without scarring the dish).
Like some other plants of the genus Diospyros, older persimmon heartwood is black or dark brown in color, in stark contrast to the sapwood and younger heartwood, which is pale in color.
