est low angle block plane I ever used.
Very well made , stout, sharp and easy to sharpen. Fine tuning it is a breeze. I've had it's poorer cousin for about thirty years and just now it needs an overhaul.
ProsWell built stout. It does exactly what I ask it to do, and does it very well.
ConsNo Dislikes.

Stanley 12-139 Sweetheart block plane is trully a Sweetheart
I am building new cabinets and this plane worked great right out of the box. I read a lot of reviews and expected to have to flatten it's base, etc. Non of that was necessary.

Great price for A fantastic tool
Have been using the standard Stanley Low Angle Block plane and thought it to be an indispensable tool for woodworking. Had seen reviews of the Sweetheart line and kept wondering how much better it could be. With prices typically around $100 never made the change. At more than $30 less than elsewhere, combined with the free shipping promo, decided to give it a try.

The feel is so much more substantial, the tool quality is beyond expectations, and the out-of-the-box performance has been so good I wish I had gotten this plane when I saw the first review.
ProsPerformance, quality, the feel of the tool while using it.
ConsTook a while to figure out the best set up initiall. Once done, it's a cinch. A little more direction in the instructions on adjusting the lever would have been helpful.

Exactly what I was looking for
First I would like to say that I received my plane very quickly. Right out of the box, I put it to work on a piece of red oak. I was shaving end grain with very little chatter in nice, thin curls. After a little work on the wet stone, this little block plane is now unbeatable. I think it looks pretty good too. I definitely recommend this tool and you're not going to beat this price unless you steal it.
ProsLooks good, good weight to it, comfortable feel, works great as long as you can sharpen an iron

Good buy
Tuned the blade and christened it on a table repair job. It held its edge, didn't migrate and shaved some very nice thin slices. Keep this one locked up and don't let the grandchildren play with it.
ProsQuality construction
ConsEasy to lose a grip if you are not paying attention.

New Sweetheart
Regardless of what any tool snob tells you, cost is secondary to performance and this plane performs right out of the box. A little honing and you're ready to work. Great little plane at a great price. I expect to get years of service out of this thing.
Prosprice, weight, good iron, comfortable grip
Conscheap cap iron
