It should be stated here that ratcheting crimpers are designed for the terminals to be inserted in one direction only. Generally for right handed operators. The dual crimp shown above, is intended to crimp the terminal in the two places of different diameter on the insulated terminals. Those of us that are left-handed must cope with the crimper. Since they are ratcheting, all operators will crimp exactly the same way. With manual crimpers that is simply not possible. Experienced electricians using the tool everyday know the difference. Students who only use the tool for a few weeks in the spring won't remember the "feel" from year to year.
