Regular care and maintenance is essential if you want the best performance from your bonsai tools. Proper care will prevent the need for costly repairs or replacements. Store your tools inside at all times. Don’t drop your tools.
Don’t twist or wrench shears and cutters during cutting. This throws the blades out of alignment and ruins the tools.
Clean your bonsai tools after each use with soap and water or rubbing alcohol. Remove resistant sap with a little turpentine.
Always dry your tools and oil lightly after each cleaning.
Keep cutting edges free of nicks. Sharpen edges only if necessary and remove as little metal as possible — the tool will last longer.
