It does work for me, so something else might be the problem. Could you provide the full item file?

id = config.getItemId("SuperPicaxeId"); name = "SuperPicaxe"; harvestLevel = 3; creativeTab = "tools"; toolClass = "pickaxe"; full3d = true; hasEffect[0] = true;

maxStack = 1;

displayName[0] = "Long pickaxe"; addToCreative[0] = true; damage[0] = 4; efficiency[0] = 16.0; maxDamage = 5000;

onHitEntity[0] = "itemstack.damageItem(1);"; onBlockDestroyed[0] = "itemstack.damageItem(1);";

textureFile[0] = "superpicaxe.png";

I am found error - mod "orechange". But I cant harvest blocks with gui interface. For example - furnace.

toolClass and harvestLevel have to have the [0], too. Adding that should fix your problem.

Edit: This isn't correct. They don't have a [0].
