Helpful tools for construction job

My brother is a construction worker. He has been doing it for years already and has several tools for construction. Just recently he was hired to construct a house and have lots of cutting woods and metals to be done. He is having some hard time in cutting because his tools are not in good condition because he has been using it for years already. The brother is looking for more cutting tools to be used for his job. Having more tools is very helpful to make his job easy and fast and of course to have clean and better results after cutting the woods and metals.
