Germany
The Stihl company, Headquartered in Germany makes all Stihl tools,including chainsaws.
Stihl saws are high quality chain saws with various models and features. You can purchase them from 349.99 to a price ranging in the thousands. They are useful for cutting trees.
A Stihl concrete saw is not hard to be found. Stihl has their own shops but also Stihl saws are found in the popular department stores. Home Depot and Lowe's are both options.
Some Stihl chain saws have an adjuster underneeth the saw to turn up the oiler .
It stands for Anti-Vibration. I have two Stihl saws made in the 80's (an 015AV and an 034AVSuper). The 034 replaced a really old 041 without the AV, so I can attest that it really makes using the saws a lot more comfortable if you plan on using it for more than an hour or so at once. But then again, all the new Stihl saws have the AV now :o)
Some Stihl chainsaws are, in spite of them being a German company.
I like Stihl but it would really be a matter of choice. Husqvarna makes some pretty killer saws as well.
Yes stihl does make high qulity garage work benches. You can expect to pay between 50-200 for a good work bench. No, Stihl makes all types of saws. You can purchase work benches at Home Depot or any other hardware store.
Along with hedge trimmers, STIHL offers a wide variety of products for sale. Some of these include chain saws, leaf blowers, deflectors, trimmer line, guide bars, saw chains and specialty saw chains for every possible need one could have.
You would have to contact the maker of that saw.
Efco makes Efco chainsaws, they are an Italian company. Their chainsaws are excellent pro level saws that compare directly with other top manufacturers. They use to make saws for John Deere until 2007 when JD signed a contract with Stihl. They can found under other names such as Olympic I believe.
