Since we have a stump grinder now and have been cutting blowdown trees from stumps, thought it might be a good investment to buy a couple carbide chains. We got 2 different brands, both 3/8", .050 84DL for the 25" bar. Forester from Amazon and Stihl Duro from eBay... The Forester chain has big carbide insert on front... It feels kinda dull...Haven't tried it yet Stihl Duro 3 had carbide insert all the way back, with a chamfered corner I know it's a green link safety type chain, but it felt sharp out of the box. It actually surprised me with how well it cut a big white oak crotch (almost like noodled) and then the log from the stump. The Forester chain (China) was $65, the Stihl was $105, this is with tax... I checked with Rappco, they make chains for emergency personnel and such...their prices were $199...... We'll see how they perform and how they last...
