It is awkward and unrealistic to have to switch books in mind in order to switch from melting ores and making stocks to crafting weapons or shields.  I suggest that those with the needed skill have the ability to stack books in mind, allowing one to move quickly from making a stock to using it in crafting.

Longsword deltas can no longer be heated beyond first level of heating, making it impossible to produce a brittle sword blade or to recover the stocks.  Also, the larger axes disappear when assembled on the table.  I havent tested in the last 2 weeks, but knife blades could not be made into brittle blades, though there is no problem making dagger blades.  I know the longsword and axe problems have been reproduced by more than one crafter.   Is there any fix planned for these problems?
