Sawing slabs

[Muskyman]

I’ve got some obsidian that I was gifted and I also have a brick/tile saw that will throw water to cut it with.
Some of the obsidian is black with silver stripes through it.  Cut it with the grain or across it? I thought about cutting across the grain but was wondering if that might make it weak. It would definitely make for a cooler looking slab.
Any thoughts?
Thanks for your input, Mike

Ended up cutting with the grain because of the shape of the pieces. Here’s what I ended up with. Big thanks to YosemiteBen.
The longer pieces are about 7 inches

Those look nice. Now, let the fun begin...

It already has 😀
My first attempt at a slab knife blade. It’s not done but it’s a start

Thanks fella’s, it’s still a work in progress.
Special thanks to you Ben for the awesome obsidian. Didn’t get to make Yosemite this year but hoping for next year around this time of year. Maybe go up to the sequoia forest too.
