With years of architectural type drafting, I have quite a collection of pencils, triangles, tools,etc.
I probably own 20-30 (50?) pencil sharpeners. And I can tell you where 1 is at the moment. I think I even remember buying an electric one at some point.
I prefer a .7mm mechanical pencil, at least the quality of a Pentel, for pattern drafting. .5mm is too thin for the paper I use. I prefer 2H lead. I use $1/roll brown postal/craft paper from the dollar store as recommended by Rory Duffy (Irish Savile Row trained tailor) when he was teaching/working in NYC. I've paid 4x as much for similar paper and always get lesser quality when I do.
I also bought a $1 pack of 12 fine tip children's markers that I use once I'm happy with the pencil draft and also to label pieces and make notes. The color is holding up fine and doesn't do anything funky if I need to press a piece flat.
I use 3M Magic Scotch tape to tape things together permanently as it doesn't discolor and go gunky over time.
By pure luck, I happened upon a roll of green "Frog Tape" made for house painting, and it seems virtually identical to drafting tape I purchased decades ago. I use it to tape paper to my cardboard cutting board and to tape the pattern paper onto the brown paper and it all peels apart easily without damaging any of the paper. The pieces can even be reused.
A Click eraser is also handy to have.
I don't actually trace patterns, I transfer them into the brown paper with pinholes, or the super pointy tracing wheel. Most of the drafting is from scratch.
And of coarse, dedicated paper cutting scissors.
