Hello, currently ingame the Blade of Saeldor uses 1 crystal shard to give 25 charge with a max of 2.5k charges.
With a somewhat recent update on osrs this was changed to give Blade of Saeldor 100 charges per crystal shard with a max of 20k charge
This will be a good QoL update as grinding crystal shards isn't the most enjoyable thing to do. For people who do not have a Ghrazi Rapier this will allow them to use the weapon more and not worry about using a bulk of crystal shards to keep the blade active.
