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.
Re: Are snap-on tools really worth the money...... I own both snap on and craftsman and I have had most of both sets for nearly 12 years. I paid $1300 way back in 95 for my snap on set and that was just the basic hand tools.p untill this point every time I buy tools, I buy the least expensive ones that still have a lifetime warranty. I'm soon starting an entry level position at a shop and I need a real set of tools, a good starter set. We get a 50% discount on all snap-on tools through school, but they are still damn expensive.
