Britain did not convert to the Gregorian calendar until 1751, when 11 days had to be added to their dates to get the Gregorian dates. In 1639 they were 10 days behind the Gregorian calendar.
Re: Klein Tools Or Greenlee. Both Klein and Greenlee are TOP quality tools with a niche market. They have a few common tools (such as rabis and ratchet cutters) and either is worth buying over pretty much anything else. They are not really direct competitors. I prefer Knipex for most hand tools except linemans.
The right tools make pruning easier and help you do a good job. Keeping tools well-maintained and sharp will improve their performance. There are many tools for pruning, but the following will probably suffice for most applications: 1  A good pair of pruning shears is probably one of the most important tools. 2  Cuts up to 3/4 inches in diameter may be made with them.
