Received this in great time- I have no problem with the seller:-)BUT! The inside of the case lists all types of materials this can cut including metals, which is what I got it for.One punch through soft 26ga copper sheet and the edges of the punch bent & in some areas, flaked off. The second disk I cut did it in completely. I had to file all of the edges and it probably would have been easier to cut the sheet with shears.So, not for metals.However, I can see it would be great for leather, paper & plastics.To me it was worth the money spent on the chance that it would actually cut metal disks.

If you need a grammar reference, this may well serve until you find a better one. It might be of greater utility if the tone wasn't vaguely condescending and pedantic, and it eschews the panoply of actual examples in favor of definitions. To wit: the 2nd person singular present perfect conjugation of "to love" results in "If you have been loved..." gives me one (singular) example but not the rationale of when to use this. The density of the text preceding the example conjugations will require your own self-study to master (if you must) the ability to spin off a subjunctive 3rd person plural present tense conjugation.The best recommendation I can offer for this is as a companion for language learners who need a quick reference for English analogs of other-language conjugations, such as when you try to conjugate "falar" and need to know which one to use.--#
