The present invention relates to tools and pertains particularly to mulitple tools mounted in a common holder.
Many workmen, such as carpenters, machinists, etc., require various tools for carrying out their tasks. A number of these tools have blades or points that wear with use and require frequent change. It is therefore desirable that the blades or the like be easily replaceable.
The tools for these workmen must be ready at hand in order to enable them to function most efficiently. For this reason carpenters and the like typically carry special belts or aprons having numerous pockets. These however, still limit the number of tools that can be carried by an individual. It would frequently be advantageous for two or more tools to be integrated into one body or holder when possible.
Tools must be affordable in order to be readily available to the average workmen. In order for a tool to be affordable, it should be simple, easy to manufacture and have easily replaceable parts. The tool must also be rugged and have a long life in order to be practical.
Accordingly, it is desirable that simple, inexpensive, yet rugged multiple use tools be available.
