I normally use a 2.5X or 3X machinists loupe. These magnifications are sufficient for the purpose and easier to use than high mag jeweller's loupes.
If you pick at the filling material with a needle and watch through the loupe, you can usually see the composition and consistency of the material. If its just dirt and rust, it picks away quite easily, but if it is a modern exoxy based filler it tends to stick together and you break little bits of it off, if it is plastic steel its almost impossible to pick it away. But then there is the possibility that the material was put there during a recent renovation to protect the ganja and blade from further erosion:- just finding a modern material in place does not necessarily gaurantee that it is a modern blade, its only an indicator that it might be. Whether the material is there to fill, or just to give protection, the end effect is that the adhesive qualities of the epoxy resin will assist in firmly fixing the ganja. Really, the only way you can be certain what it is , is by close physical examination. As has already been demonstrated in another thread, photographs are a very poor substitute for having the thing in your hand. |
