have a read through the tutorials and see how to construct a knife but dont get hung up on teh use of belt sanders and pillar drills etc the just make the job quicker and easier.
All the tools you need are a drill with a small bit say 3 mm, a rasps, files and sandpaper.
Do not try and be overy complicated with your design but do not try a one piece handle. depending on what blade you have will decide how easy the job is but its not that hard. A factory blade and a factory bolster makes it easier BTW.
So what is the blade you have a name and isze and/or pictures wil help.
The tutorial with the blade with the swirls (damascus) was done by a genious of a knifemaker do not expect such things from yourself.
This is my first knife it has gap between the antler and wood and the handle is far too big but it will always be that way as it was my first but all could be sorted easily if it was necessary.
