I’m in the market for a Flat Top Grind Blade. I’m looking for something to give me good square cuts for tenons, splines for boxes, and other applications. Bear in mind that alot of these cuts will be cross grain, so I’m not sure a FTG Rip blade is the answer. Any recommendations?

Call Forrest Blades (1-800-733-7111) they'll custom grind a blade to the pattern you want, I believe for the price of the same blade with a stock tooth pattern.
For cross grain work, the blade will need some kind of bevel teeth followed by a raker which is a standard pattern, except that the bevel teeth normally are taller than the raker which leaves small grooves on the bottom of the cut. Perhaps a blade with the rakers as tall as the cutters would work without to much tearing.

I have a 36 tooth Freud General Purpose blade that I use for the similar purposes. It was inexpensive and works well.
I you have an older blade you like but it needs to be sharpened, you can request that your local sharpening shop grind the blade flat on the top.
Freud's full kerf 24 tooth rip blade is a flat kerf design.
Since I'm a Sharpologist, I have the luxury of customizing my own blades.On an avg. 50 tooth combo blade the raker is .007-.010 lower than the alternate bevel teeth.If you have one and it needs sharpening,ask your saw shop to make the raker only .001-.002 lower.And it does need to be lower or it will affect the cut(tearing) out.

It is not cheap. I've been using one for a while, I also have a Forest WWII. To me, the In-Line blade is just as good. To the eye, the tooth geometry is identical to the WWII, but, there is a raker (ATBR). So it cuts just as well as a WWII, but with a flat bottomed kerf.

I do a lot of the same... and just got my Forrest WWII FTG blade delievered last week. All I can tell you is "Wow". Cross grain on white oak left a cut so nice it felt sanded. I can't even begin to count the amount of tenons I've cut in the last week... and it is excellent. I got it on-line at...

Ordered over the phone, anyway, and they were great to talk to. This might sound a little sad- but given the amount of tenon work I do I'm going to buying another one when it comes time to send it back for sharpening. The model number is W21001.
In short I would give it a 9.8 outta 10. Hope that helps!
PS- I also got their zero clearance insert, cuz' it was cheap and figured I would have one just for this blade. Very, very nice.
I use my dado blades to cut tenons. It works perfectly well with a quality set, and the whole cheek is removed in one or two passes using a stop set up on the miter gage fence.
