Every curved LEVEL5 finishing trowel here is 0.7 mm, every flex blade 0.4 mm and every ultra-flex 0.3 mm.
If you want a curved blade thinner than 0.7 mm, none of these has one. Blade thickness differs from curve.

Blade profile changes even when trowel length stays the same
The 12" Ultra Flex Finishing Trowel with 0.3mm Blade shares its length with flex and curved alternatives. Across these trowels, thickness spans 0.3 to 0.7 mm and length spans 12 to 16 in. Read the curved, flex and ultra-flex labels alongside thickness rather than treating the longest blade as the same tool with more reach.
Width variants need attention at purchase
Flex Finishing Trowels have different width variants even when their displayed length and thickness coincide. Keep the width in the model name when ordering. Blade deflection and the finish you will achieve remain unquantified by the maker's profile labels; compound application was not assessed for this comparison. Use the model's intended-work and care instructions, including safe handling of its blade edges.
Before you buy
How do the two flex trowels at each length differ?
By blade width, as far as LEVEL5's names go. The 4-965, 4-966 and 4-967 carry the narrower blade and the 4-974, 4-975 and 4-976 the wider one, at the same thickness. Nothing else in the names separates them, and every profile comes at each of the three lengths. Every curved LEVEL5 finishing trowel here is 0.7 mm, every flex blade 0.4 mm and every ultra-flex 0.3 mm. Profile and thickness go together. The flex trowels also come in 100 mm and 120 mm blade widths, told apart only by the product names. If you want a curved blade thinner than that category’s thickness, none of these has one.
What's curved on the curved trowels?
The blade, going by LEVEL5's names for the 4-971, 4-972 and 4-973. How much curve isn't stated, so you'd judge that from the product photos.
Will a thinner blade give me a smoother finish?
It might, but nothing here shows it. Thickness is a dimension LEVEL5 prints in the product name, with no finish result attached, and ultra-flex is the thinnest of the three profiles.
