NK42 "New Kid"

Dense and hard, the most common pro wood. Hits hard and holds up when the player squares the ball up; breaks rather than flakes when mis-hit. Quality varies a lot by maker.

Tip: Maple from a good maker is the best wood bat money can buy; maple from a cheap one is the worst.

Drop is length minus weight: a 30 in, 20 oz bat is a -10. A bigger drop number means a lighter bat for its length. Younger players use -10 to -13; USSSA 13U is usually capped at -5; high school and college are -3.

Tip: Check the drop your league allows before you look at anything else.

A thinner barrel (under about 2.45 in on a wood bat), with less wood to hit with. Its size does not decide the balance: some skinny-barrel bats are end-loaded.

A handle near 1 in or more. It feels closer to a metal bat, takes sting out of mis-hits, and in wood it lasts longer. Makers recommend it for players moving from metal to wood.

Tip: If your player is switching from metal to wood, start here.

The handle widens into the knob like the bell of a trumpet. Players who choke up or want leverage like it; it also keeps the bottom hand from sliding off. Popular from high school up.
