Knocking in compresses the fibers of a new willow bat so it can withstand a hard leather ball. Lightly oil the face and edges if the maker recommends it, then strike the bat with a bat mallet for several hours, gradually harder, paying attention to the edges and toe. Finish by facing old, soft balls in the nets before using it in a match.
A brand-new willow bat is too soft to face a hard ball. Knocking in protects your investment.
What you need
- A bat mallet (wooden or rounded).
- Raw linseed oil, if your bat needs it.
- A few old, soft cricket balls.
- Time: several sessions over one to two weeks.
Step by step
- Oil lightly (only if recommended): a thin layer on the face, edges and toe, avoiding the splice and stickers. Let it dry flat for a day.
- Start gently: tap the face with the mallet, gradually increasing force over the first hour.
- Round the edges: strike edges at an angle so they become rounded, not flat.
- Protect the toe: tap gently and never strike the toe end-on.
- Build up force over several sessions.
- Net sessions: face old balls and short catches before match use.
Signs it is ready
Seam marks on the face become shallower, and edges show gentle marks rather than deep dents when you strike old balls.
Look after it
Store it at room temperature, avoid damp, and consider an anti-scuff face sheet and toe guard.

Common questions
How long does knocking in take?
Many makers suggest around 6 to 8 hours of mallet work in total, spread over several sessions. Follow the maker's instructions for your bat.
My bat says it is pre-knocked. Do I still need to knock it in?
Usually yes, but for less time. Pre-knocked bats still benefit from some mallet work and net sessions with old balls.
Should I oil my bat?
Only if the maker recommends it, and lightly. Bats with protective face covers often need little or no oil. Too much oil makes the bat heavy and dead.
Are edge cracks normal?
Small surface cracks can appear. Deep cracks or splits should be repaired before further use.
