The keyblade is made out of wood and definitely has some weight to it, but it is convention safe and hardly used at all. It's also very sturdy due to the wood.
Here's the actual keyblade that I'm selling.

Measurements:
Overall length-56 inches
length(without chain)- 40 inches
chain length- 16 inches
"claw" length-14 inches
"claw" width-9 inches
lion mane width- 8 inches
handle length- 9 1/2 inches
handle guard to handle guard- 12 inches
If you need any other measurements, I'll do my best to get them to you.

Now for reference as to what it looks like in person here is the other one that I'm not selling,

Since it took so long to make I'd really like to sell it for around $150 (not including shipping since it's such a heavy item)
~Thanks for looking!
