Next sword after Longsword? I started as a Warrior and love the small(ish) shield and one handed sword.  Great for blocking and countering as the sword is nice and fast.  I've upgraded it to +7 and have just rang the second bell so need to head to Sens Fortress (or perhaps explore other paths such as Catacombs or Valley of Drakes).

However I'm having a hard time finding a better weapon.  Where can I find a better weapon similar to the longsword?  I realise as my longsword is +7 so does a lot more damage than perhaps new weapons I find, but I guess can I easily upgrade any new found weapons to at least +5 quite easily through buying upgrade component from the blacksmith.
