2. We perform two-hour hand-knocking using mallet and between knocking apply a small amount of Linseed Oil. This could cause actual color of bat to change due to oil and surface may show knocked-in marks which is normal.
3. We smooth out sharp edges and apply scuff sheet.
4. We highly recommend using knocked-in bats in couple of net sessions before using it in a game.
5. Bat weight may change slightly once extra grip, scuff sheet is installed and linseed oil is applied.
