Rune Short-sword on Accurate, or Rune Longsword on Stab/Controlled. They're about equal in Attack. Rune Longsword will hit higher.
In my opinion the best is a rune scimatar
Sword: Rune 2handed sword. Shield: Rune Berserker shield 100.
Probably the Rune battleaxe, though the Warhammer is slightly stronger against plate armor.
The overall best f2p Runescape weapon is actually a range weapon - Maple Longbow (sighted). It has a range bonus of over 100. The best f2p degradeable weapon is the Gravite 2h. Both are Dungeonneering weapons and need 45 Dungeonneering levels.
A Rune Scimitar, mainly because of speed and attack damage rates.
A Rune 2h is a good weapon for a high lvl strength person on Runescape. A rune scimitar is a perfect weapon for a lvl 46 attack because it is designed for attack.
Weapons don't add to your defence bonuses. The best armour, however, would be full rune.
For F2p it would be the Rune 2Hander as it has the highest str bonus, but i prefer the scimitar:D
Rune Scimmy if you go for speed and what the def boost from the shield. Rune 2h for pure strength but slower speed. Rune Battle Axe for more strength then the scimmy alittle bit slower but can have a def with shield.
Ranging: Problaby Maple Bow with rune arrows Magic: Fire staff maybe Melee: definetly Rune 2h sword (disadvantage: it is the slowest rune weapon for F2P and you can't wield a shield with it). Instead I would recommend Rune Scimitar with the Rune Kiteshield (regular), (g) (t) or Rune Shield (h1) (h2) (h3) (h4) (h5)
