A 2-ft. four-fold boxwood rule (Fig. 6) is the best for the all-round purposes of the joiner; and for those who can use the slide rule, the tool shown by Fig. 7 would be handy. A simple 2-ft. two-fold rule (Fig. 8) is cheaper, but it is the greatest economy to buy the best tools, and for that reason perhaps the rule with double arch joints shown by Fig. 9, though costing more than twice as much as the one illustrated by Fig. 6, will be found the best and cheapest in the end. The average worker will find a simple rule preferable to an elaborate one. Fig. 10 shows a combined rule and spirit level, the rule joint also being set out to serve as a protractor. This tool may prove useful in special circumstances, but its use as a spirit level is not recommended, it being preferable to have rule and level two quite distinct tools.
