Tool Care

Power tool batteries should be stored at a moderate, stable room temperature, partly charged rather than full or flat, away from direct sun, metal objects and anything flammable, and kept in their original case or a dedicated holder so the terminals can’t short against anything. Heat and full charge are the two biggest shorteners of … Read more

A bench grinder removes metal fast to reshape a damaged or badly worn edge, or to reset a bevel angle. A sharpening stone removes metal slowly and precisely to put a fine, controlled edge on a tool that is already close to right. Most sharpening routines use both — grinder for shaping, stone for finishing. … Read more

Before a warranty ends, run the tool through its full range of functions, listen and smell for anything unusual, check the cord or battery and charger, inspect any guards and safety switches, and confirm accessories and paperwork are in order — while a repair or replacement is still free. Why does this matter more near … Read more

A tool is genuinely worth repairing when the fault is specific and fixable, the parts or labour cost meaningfully less than a comparable replacement, and fixing it does not mean patching around a safety feature. If the fault is a worn motor, a cracked casing near moving parts, or unknown internal damage, replacement is usually … Read more

Storing a lithium-ion battery at full charge keeps its internal chemistry under higher voltage stress for longer, which speeds up the slow, permanent capacity loss that all these batteries experience over time. A pack left topped up on a shelf for months will typically hold less charge than one stored partly discharged. Why does full … Read more

Lithium-ion tool batteries age mainly from heat, deep discharge cycles and time spent sitting at full charge — not simply from being old. A pack used gently and stored at a partial charge in a cool place will outlast an identical pack that’s regularly run flat, charged hot, and left topped up on a shelf … Read more

Camellia oil is a light, non-drying plant oil pressed from the seeds of the camellia tree, long used in Japan to protect tool steel from rust. Woodworkers apply a thin film of it to plane blades, chisels and saw plates because it resists gumming, doesn’t turn rancid, and won’t stain wood if traces transfer to … Read more

Rust does more than stain metal orange. It eats into the surface of the steel itself, which means it removes material permanently rather than sitting on top of it. On cutting edges that ruins the geometry that makes a blade sharp. On moving parts it adds friction and grit. On measuring tools it can quietly … Read more

Sharpening removes metal to create a new edge on a blade that has gone dull, chipped or rounded over. Honing is the lighter, more frequent step of refining and realigning an edge that is already basically sound. Sharpening rebuilds the edge; honing maintains it between full sharpenings. What is the actual difference between honing and … Read more

A saw blade goes dull mainly from heat and friction, not simple mileage. Cutting resinous wood, hitting embedded grit or nails, feeding too slowly, and letting pitch build up on the teeth all raise the temperature at the cutting edge, which wears or micro-chips it faster than clean, well-fed cuts through the same material ever … Read more
