It is a strange but true fact that you are more likely to injure yourself with a blunt tool than a sharp one. This is because a blunt tool needs to be forced more, increasing the risk of slippage and therefore the risk of stabbing or slicing yourself. For this reason, if not for any other, you really should take care of your tools. It is very easy to have the best of intentions when you have a new tool, carefully cleaning and storing it after use. Before long, however, you just throw the tool into your toolbox with everything else: I know because I've been there and done that. The amount of money I've wasted on buying chisels and router cutters to replace their predecessors which I ruined through lack of care...! Anyway my top tool safety tips are as follows:
If at all possible, go on a woodworking course at your local college. Most have evening or Saturday courses for beginners, and will often allow you to work on your own projects after you have learned the basics.
Look after your tools and keep them sharp. Don't forget to oil cutting edges to keep rust at bay.
Don't use tools, particularly power tools, if you are tired or unwell.
Keep your workspace clear of hazards so you don't trip.
When you buy a new tool, particularly a power tool, read the instructions before use. Even better, get the retailer or manufacturer to demonstrate the tool before you buy.
Never forget that more people are injured using woodworking equipment than with any other machinery.
