Of all the clubs in a bag, the putter is the one most golfers leave exposed, no headcover, bouncing around against irons and the inside of the bag between holes.
What that does over time
Face inserts on modern putters are softer than they look, and repeated contact with other clubs leaves dings that can affect roll consistency and resale value down the line.
The fix
A simple headcover solves it. The GolfRoots blade headcover comes in three styles, Dancing, Cursive, and Goosebump, with a soft synthetic lining built to protect blade-style putters specifically.
$14.99, and it's the kind of small purchase that protects a much bigger one.
