These are actions for personal injuries alleged to *249 hаve been sustained by the plaintiff on July 19, 1965 while using a radial arm power saw which he purchased from the defendant Sears Roebuck and Co. under its brand name Craftsman and which had been manufactured by the defendant King-Seeley Thermos Co. Thе writ against King-Seeley contains two counts, one based on strict tort liability and one on implied warranty at commоn law. The writ against Sears contains three counts: one in strict tort liability, one for breach of implied warranty under RSA 382-A:2-314, аnd one for breach of implied warranty at common law. All counts allege that the saw was “ so defectively dеsigned and manufactured as to be unreasonably dangerous to the user, ” in that the saw blade would, when pulled toward thе operator, extend over the edge of the table, and also alleged that plaintiff’s hand was injured by the saw while he was holding a piece of wood being cut.
The defendant King-Seeley manufactured the saw in Michigan. Plaintiff ordered the saw from Sears’ place of business in Georgia and it was delivered to him in his winter home in Florida. He shipped it tо his summer home in New Hampshire where the accident occurred.
The Trial Court (Keller, J.), transferred five questions asking whеther any of the counts stated a cause of action, whether contributory negligence was a defense tо any of the counts, and what law governs die trial of this case.
The questions whether the counts based on strict liability in tort stаte causes of action and whether contributory negligence is a defense to such an action are аnswered in the affirmative by the recent decision in
Buttrick
v.
Lessard & Sons, Inc.,
Buttrick v. Lessard & Sons, Inc., supra, was a case in which. the plaintiff had actual knowledge of the alleged defect and the question of his contributory negligence related to his conduct in view of that knowledgе. The record before us does not reveal what knowledge the plaintiff in this case had of the alleged defect or danger. However we reaffirm the doctrine that failure to discover or foresee dangers which the ordinary person would have discovered or foreseen as well as negligent conduct after discovery of the danger and in the use of the product will constitute a defense to an action based on strict liability.
Defendant аrgued that in the event this court embraced the doctrine of strict liability in tort, the ruling should be prospective

Defеndant argues that the counts based on common-law implied warranty of fitness and quality should be dismissed because no such warranty has existed at common law in this state.
See Reed
v.
Prentiss,
Count 2 in the writ against Sears Roebuck and Co. states a cause of action based on breach of implied warranty undеr RSA 382-A:2-314 winch is based on the Uniform Commercial Code. The defendant argues that this count should be dismissed *251 because of failurе to allege that notice was given within a reasonable time to tire seller as required by RSA 382-A:2-607. However, it appears that both plaintiff’s original and amended count No. 2 do allege such notice. We therefore need not decide whether such an allegation is required or whether the absence of such notice is a matter to be rаised in defense.
Contrary to the contention of the plaintiff, we hold that contributory negligence is a defense to an action for breach of war - ranty under RSA 382-A:2-314 in the same manner as in actions based on strict liability as above dеscribed. See RSA 382-A:2-314, Comment 13; s. 2-316, Comment 8; and s. 2-715, Comment 5.
This leaves unanswered the question as to what law governs the trial of the casе. We hold that New Hampshire law will govern all aspects of the trial. The injury which furnishes the bases of the counts on strict liаbility occurred here and we find no reason to apply any- other law but ours.
Clark
v. Clark,
The count based on breach оf implied warranty under RSA 382-A:2-314 is governed by the Uniform Commercial Code. No conflicts have been suggested between the law of this State and that of the other states involved with respect to this count. The fact that the injury which gave rise to thе cause of actions occurred here gives this State an appropriate and significant relationship to the transaction. Since there was no express choice of law made by the parties the application of our law to tire trial of this case is justified.
