Hand tools
Browse guides by topic and find the next step for your project.
This hub covers the tools you hold and turn yourself: screwdrivers, wrenches, pliers, hammers, knives and multi-tools. It shows what each one is for, how to tell the types apart, and how to keep them sharp and working.
A lot of hand tool trouble starts with the wrong fit. A Phillips bit in a Pozidriv screw slips out under load. A worn bit chews up the screw head. A dull blade needs more force, so it skips. The guides start with picking the right type, then how to use it.
How to pick a guide:
- Bits keep slipping? Types of screwdrivers shows how to match the bit to the head.
- Not sure what a blade on your multi-tool does? See what the awl on a multi-tool is for.
- Dull blade? Learn how to sharpen a titanium-coated knife without wrecking the coating.
- Clearing out the garage? Where to sell used power tools covers where to sell and how to price.

Safety basics for this job
- Wear safety glasses. Bits snap and chips fly. OSHA requires eye protection at work for flying particles, and it makes sense at home too.
- Use each tool for its own job. OSHA warns that a chisel used as a screwdriver can break, and the tip can fly off. Don't pry with a screwdriver either.
- Retire worn tools. OSHA says to replace splintered handles and keep chisel and punch heads free of mushrooming.
- Insulated doesn't mean live work is OK. A 1000 V-rated screwdriver adds a layer of protection. Still turn off the power and test that it's dead first.

How to sharpen a titanium-coated knife (without wrecking the coating)
A titanium-coated knife is steel under a very thin coat, so you sharpen it like steel. Use a stone or hand sharpener at 15 to 20 degrees; spare the flats.
