rav yehuda - building an oven

acc to tosfos greifas hatanor is the final blow of making the oven. does this mean that acc to tosfos one may also build an oven from scratch acc to rebi yehuda? and if tosfos agrees (to the ran) on this point, how is this different?
note: i did find an argument between the rosh and ran if acc to rw yehuda you may sharpen the knife on a stone thing and the kurban nesanel explains that acc to the rosh sharpening the knife is no more 'long term' then many breads in an oven wich is mutar bec it helps the bread. does that mean that any building of dishes is mutar acc to rw yehuda?

i am not sure how you see from tosafos that you can make an oven from scratch. although on a torah level it may be included in machshirei ochel nefesh and mutar, but on a d'rabonon level it would be no better than sharpening a knife that was completely dull which the gemara says is assur and rashi explains m'drabonon bec. of excessive tircha. it would seem that forming any kli from scratch would at least be assur for the same reason.
