Dclaws is not a weapon you should train attack with, there only use is there spec. I suggest using brakish blade or d scim if you have one Monkey Madness, untill you get 70 attack. I also suggest when your combined strength and attack reaches 130, to go and earn the dragon defender at warrior's guild, as its a really good offhand weapon to train with.
If you are only 64 attack, i suggest going to gigant spiders, they are located in the third level on the Stronghold of Security. They are very afkable, so you get to do other things while training.
