In Savage Worlds there are several 2-handed meleé weapons and most of them have an effect on the character´s parry. For example, fighting with a Great Sword requires 2 hands and lowers your parry by one point while fighting with a Spear requires 2 hands and increases your parry by one point.
In some of the settings (I think the first one was 50 fathoms) there is an edge (Oversize Weapon Master) that allows characters to use a 2-hand weapon in one hand ---without suffering a -4 penalty.
I wonder if using a 2-handed weapon with this edge should erase the effects on parry, both positive and negative. It seems intuitive to me that being able to use a sword or an axe with one hand means that you have more control on the big weapon (thus negating the -1 on parry) while using a spear with just one hold means that you cannot make as much stopping force as with two holding points (thus negating the +1 to parry).
I have not seen anything relevant in the core rules (but I do not have access to 50 fathoms or the other settings) nor have I found any official position on this in the forums. If anyone has the right setting that clarifies this issue or has found anything relevant from an official source, I would be very grateful to know.
