As you might have already guessed with the advent of the plastic BaneBlade, Forgeworld have been working on conversion kits which use the new plastic kit.
This is Daren Parrwood’s work in progress of a Shadowsword conversion kit.
The target price is £90-£100 which is two thirds of the price of a full resin Shadowsword, but has the advantage that the plastic part of the kit should be easier to put together than the resin parts of the current model.
Certainly there are other conversion possibilities as well including Ork looted versions and Chaos versions.
