re: What kind of hand saw for this job?

I have one of those but I have trouble keeping it straight. Same one – the shark. Got it on Amazon a couple of years ago. I use it all the time. That’s how I know I can’t make it cut straight. :-(

I found a fat max backsaw on Amazon for $15. Looks like it should fit the bill. I guess if nobody has any objections or better suggestions I’ll order it tonight. The price is right.
