This a fairly "specific-use" tool, but really top flight. They used to be called butcher-block planes because they were used mostly to flatten endgrain maple butcher block. I carve large pieces of poplar with alot of end grain glue joints and with my regular compliment of planes and sanding equipment, I wasn't able to get really dead flat joints. The low angle jack plane is a very well machined handplane. It is a "simple" block plane with an iron body that has an adjustable throat, a bronze lever cap and cherry handle and knob.
The blade is a hefty 3/16 " and is adjusted with a bronze knurled screw. There is no lateral blade adjustment, but the bed is ground so true and the forward adjustment is without any slop so you dont need it. Every piece of the plane is rock solid so even on end grain you get perfect curls.
I also use this plane on tough woods (curly and birdseye maple) long and short grain with great results.When I look at this plane as a machine, with the exception of a few carving tools, nothing I own is as well made. I had always looked at $225 planes like jewelry, nice but unneccesary. But You really do get what you pay for atleast with this plane. On a 1 to 10 scale it's an easy 10. If you use hand tools extensively (you caveman!!) certainly try out one of Lie-Neilsen's planes. The only downside is the price, but it will last your lifetime. Incedentally, this plane did not need any "tuning" before use, five minutes on the blade with a leather strop and it was perfect.
