I use this filter wrench. It has a spring that allows the clamps to expand out. Have used this for many years with no problems.

Also have this strap wrench for a backup and maybe travel if the trip was for more than 4,000 miles.
I install the new filter by hand with a light coat of oil on the seal.
Use a torque wrench when installing the drain plugs.
Do you need new copper washers for each oil change... No. On my 2012 with 52,200 miles I did not change the copper washers. On my 2015 with 7.662 miles and four oil changes I have not replaced the copper washers.
Hope this helps.
