How do I get a tool to give me the name a brick when I click on it?

I am trying to make an axe be able to chop down wood but I'm struggling to figure out how to make sure if it clicks on a tree.

This is what I tried.

local playerName = script.Parent.Parent.Parent.Name
local Player = game.Players:WaitForChild(playerName)
local tool = script.Parent
local Mouse = Player:GetMouse()
local Character = Player.Character or Player.CharacterAdded:Wait()
local maxDistance = 300 
local BrickColor = BrickColor.new("Really red") 

local function onActivation()
    local Ray = Ray.new(tool.Handle.CFrame.p, (Mouse.Hit.p - tool.Handle.CFrame.p).unit * maxDistance)
    local Part, Position = workspace:FindPartOnRay(Ray, Character, false, true)
    local name = Part.Name
    print(name)
end
