How would I script a tool which would destroy a part?

How would I script a tool which would destroy a part with a certain material e.g. part.Material == "Sand"?

I made a tool which my player can hold as a starting point by adding a handle. How would I make it so that if a player touches an object with the sand material the tool in its hand the part will destroy?

how would I use the destroy() function?

Also, previously I made this code which would make the transparency of an object 1 and cancollide false so you can remove the object where you cant see it and wont collide into it but I don't know where to place it as a local script in my tool with the local script in the tool and not in the handle but when I tried nothing happened when i clicked on the part I wanted to make transparent which was called Terrain and nothing happened and I had the tool equipped.

Code I used previously:

script.Parent.Activated:Connect(function(mouse)
    if mouse.Hit.Name == "Terrain" then        step = .1
        waitC = .1
        for i=0,1 step do
            mouse.Hit.Transparency = i
            wait(waitC)
        end
        mouse.Hit.CanCollide = false
    end
end)

Thank You and help is appreciated

First make the tool. I'm not going to explain how to make a tool. Then make a part and add this script into it:

script.Parent.Touched:connect(function(hit) if hit.Parent.Name == "YourToolNameHere" then game.Workspace.Part:Destroy()

If you want to make the tool destroy more parts, add this script into other parts as well. Hope this helps!
